+Note: To enable SEPA Debit and sofort, set `PaymentSheet.configuration.allowsDelayedPaymentMethods` to `true` on the client.
+These payment methods can't guarantee you will receive funds from your customer at the end of the checkout because they take time to settle. Don't enable these if your business requires immediate payment (e.g., an on-demand service). See https://stripe.com/payments/payment-methods-guide
+
+#### Pre-fill billing details
+PaymentSheet collects billing details like name and email for certain payment methods. Pre-fill these fields to save customers time by setting `PaymentSheet.Configuration.defaultBillingDetails`.
+
+#### Save payment methods on payment
+> This is currently only available for cards + Apple/Google Pay.
+
+PaymentSheet supports PaymentIntents with `setup_future_usage` set. This property tells us to save the payment method for future use (e.g., taking initial payment of a recurring subscription).
+When set, PaymentSheet hides the 'Save this card for future use' checkbox and always saves.
+
+#### SetupIntent support
+> This is currently only available for cards + Apple/Google Pay.
+
+Initialize PaymentSheet with a SetupIntent to set up cards for future use without charging.
+
+#### Smart payment method ordering
+When a customer is adding a new payment method, PaymentSheet uses information like the customers region to show the most relevant payment methods first.
+
+#### Other changes

+* Fixes a bug where `STPPaymentContext`'s `retryLoading` method would not re-retrieve the customer object, even after calling `STPCustomerContext`'s `clearCachedCustomer` method. [#863](https://github.com/stripe/stripe-ios/pull/863)
+* `STPPaymentContext`'s `retryLoading` method will now always attempt to retrieve a new customer object, regardless of whether a cached customer object is available. Previously, this method was only intended for recovery from a loading error; if a customer had already been retrieved, `retryLoading` would do nothing. [#863](https://github.com/stripe/stripe-ios/pull/863)
+* `STPCustomerContext` has a new property: `includeApplePaySources`. It is turned off by default. [#864](https://github.com/stripe/stripe-ios/pull/864)
+* Adds `UITextContentType` support. This turns on QuickType suggestions for the name, email, and address fields; and uses a better keyboard for Payment Card fields. [#870](https://github.com/stripe/stripe-ios/pull/870)

+* The `STPBackendAPIAdapter` protocol now includes two optional methods, `detachSourceFromCustomer` and `updateCustomerWithShipping`. If you've implemented a class conforming to `STPBackendAPIAdapter`, you may add implementations of these methods to support deleting cards from a customer and saving shipping info to a customer. [#813](https://github.com/stripe/stripe-ios/pull/813)
+* Adds the ability to set custom footers on view controllers managed by the SDK. [#792](https://github.com/stripe/stripe-ios/pull/792)
+* `STPPaymentMethodsViewController` will now display saved card sources in addition to saved card tokens. [#810](https://github.com/stripe/stripe-ios/pull/810)

+
+## 11.0.0 2017-06-27
+* We've greatly simplified the integration for `STPPaymentContext`. See MIGRATING.md.
+* As part of this new integration, we've added a new class, `STPCustomerContext`, which will automatically prefetch your customer and cache it for a brief interval. We recommend initializing your `STPCustomerContext` before your user enters your checkout flow so their payment methods are loaded in advance. If in addition to using `STPPaymentContext`, you create a separate `STPPaymentMethodsViewController` to let your customer manage their payment methods outside of your checkout flow, you can use the same instance of `STPCustomerContext` for both.
+* We've added a `shippingAddress` property to `STPUserInformation`, which you can use to pre-fill your user's shipping information.
+* `STPPaymentContext` will now save your user's shipping information to their Stripe customer object. Shipping information will automatically be pre-filled from the customer object for subsequent checkouts.
+* Fixes nullability annotation for `[STPFile stringFromPurpose:]`. See MIGRATING.md.
+* Adds description implementations to all public models, for easier logging and debugging.
+* The card autofill via SMS feature of `STPPaymentContext` has been removed. See MIGRATING.md.
+
+## 10.2.0 2017-06-19
+* We've added a `paymentCountry` property to `STPPaymentContext`. This affects the countryCode of Apple Pay payments, and defaults to "US". You should set this to the country your Stripe account is in.
+* `paymentRequestWithMerchantIdentifier:` has been deprecated. See MIGRATING.md
+* If the card.io framework is present in your app, `STPPaymentContext` and `STPAddCardViewController` will show a "scan card" button.
+* `STPAddCardViewController` will now attempt to auto-fill the users city and state from their entered Zip code (United States only)
+* Polling for source object updates is deprecated. Check https://stripe.com/docs for the latest best practices on how to integrate with the sources API using webhooks.
+* Fixes a crash in `STPCustomerDeserializer` when both data and error are nil.
+* `paymentMethodsViewController:didSelectPaymentMethod:` is now optional.
+* Updates the example apps to use Alamofire.
+
+## 10.1.0 2017-05-05
+* Adds STPRedirectContext, a helper class for handling redirect sources.
+* STPAPIClient now supports tokenizing a PII number and uploading images.
+* Updates STPPaymentCardTextField's icons to match Elements on the web. When the card number is invalid, the field will now display an error icon.
+* The alignment of the new brand icons has changed to match the new CVC and error icons. If you use these icons via `STPImageLibrary`, you may need to adjust your layout.
+* STPPaymentCardTextField's isValid property is now KVO-observable.
+* When creating STPSourceParams for a SEPA debit source, address fields are now optional.
+* `STPPaymentMethodsViewControllerDelegate` now has a separate `paymentMethodsViewControllerDidCancel:` callback, differentiating from successful method selections. You should make sure to also dismiss the view controller in that callback
+* Because collecting some basic data on tokenization helps us detect fraud, we've removed the ability to disable analytics collection using `[Stripe disableAnalytics]`.
+
+## 10.0.1 2017-03-16
+* Fixes a bug where card sources didn't include the card owner's name.

+## 9.3.0 2017-01-05
+* Fixes a regression introduced in v9.0.0 in which color in STPTheme is used as the background color for UINavigationBar
+  * Note: This will cause navigation bar theming to work properly as described in the Stripe iOS docs, but you may need to audit your custom theme settings if you based them on the actual behavior of 9.0-9.2
+* If the navigation bar has a theme different than the view controller's theme, STP view controllers will use the bar's theme to style it's UIBarButtonItems

+## Migration Guides
+### Migrating from versions < 23.0.0
+* The `Stripe` module is now split between `StripePaymentSheet`, `StripePayments`, and `StripePaymentsUI`. Some manual changes may be required. Migration instructions are available at [https://stripe.com/docs/mobile/ios/sdk-23-migration](https://stripe.com/docs/mobile/ios/sdk-23-migration).
+* [Changed] If you use PaymentSheet, you must now `import StripePaymentSheet`. PaymentSheet users no longer need to import the `Stripe` module.
+* [Changed] The minimum iOS version is now 13.0. If you'd like to deploy for iOS 12.0, please use Stripe SDK 22.8.4.
+* [Changed] STPPaymentCardTextField's `cardParams` parameter has been deprecated in favor of `paymentMethodParams`, making it easier to include the postal code from the card field. If you need to access the `STPPaymentMethodCardParams`, use `.paymentMethodParams.card`.
+  * Note that `.paymentMethodParams` returns a copy, so `paymentMethodParams.card` should not be set directly. If you need to set the card information, set `.paymentMethodParams` to a new STPPaymentMethodParams:
+```
+cardField.paymentMethodParams = STPPaymentMethodParams(card: card, billingDetails: nil, metadata: nil)
+```
+
+### Migrating from versions < 22.8.0
+* `PaymentSheet.reset()` has been renamed to `PaymentSheet.resetCustomer()`. If calling the former method, follow the warning in Xcode and apply the suggested fix-it.
+
+### Migrating from versions < 22.2.0
+* `StripeConnections` SDK has been renamed to `StripeFinancialConnections`. If you included `StripeConnections` to support ACH Direct Debit payments, you will need to rename the dependency to `StripeFinancialConnections`. If you are manually installing `StripeConnections`, you will need to remove the old `StripeConnections.xcframework` and include the new `StripeFinancialConnections.xcframework`, which can be found in the [release assets](https://github.com/stripe/stripe-ios/releases/tag/22.2.0) for version 22.2.0 of the SDK.
+
+### Migrating from versions < 22.0.0
+* The minimum iOS version is now 12.0. If you'd like to deploy for iOS 11.0, please use Stripe SDK 21.12.0.
+* `IdentityVerificationSheet` now has an availability requirement of iOS 14.3 on its initializer instead of the `present` method. If your app supports iOS versions < 14.3, you will need to add an availability check for iOS 14.3 before initializing the sheet.
+
+### Migrating from versions < 21.12.0
+* `Stripe` now requires `StripeApplePay`. If you are manually installing `Stripe`, you will need to include `StripeApplePay.xcframework`, which can be found in the [release assets](https://github.com/stripe/stripe-ios/releases/tag/21.12.0) for version 21.12.0 of the SDK. If you are using CocoaPods or Swift Package Manager, these dependencies will be imported automatically.
+
+### Migrating from versions < 21.10.0
+* `StripeIdentity` now requires `StripeCameraCore`. If you are manually installing `StripeIdentity`, you will need to include `StripeCameraCore.xcframework`, which can be found in the [release assets](https://github.com/stripe/stripe-ios/releases/tag/21.10.0) for version 21.10.0 of the SDK. If you are using CocoaPods or Swift Package Manager, these dependencies will be imported automatically.
+
+### Migrating from versions < 21.9.0
+* `Stripe` and `StripeIdentity` now require `StripeUICore`. If you are manually installing `Stripe` or `StripeIdentity`, you will need to include `StripeUICore.xcframework`, which can be found in the [release assets](https://github.com/stripe/stripe-ios/releases/tag/21.9.0) for version 21.9.0 of the SDK. If you are using CocoaPods or Swift Package Manager, these dependencies will be imported automatically.
+
+### Migrating from versions < 21.8.1
+* The `Stripe` module now requires `StripeCore`. If you are manually installing the Stripe SDK, you will need to include `StripeCore.xcframework`, which can be found in the [release assets](https://github.com/stripe/stripe-ios/releases/tag/21.8.1) for version 21.8.1 of the SDK. If you are using CocoaPods or Swift Package Manager, these dependencies will be imported automatically.
+
+### Migrating from versions < 21.4.0
+* STPPaymentHandler now presents its SFSafariViewController using the `.overFullScreen` presentation style by default. To select a different style, implement the `STPAuthenticationContext.configureSafariViewController(_:)` function in your `STPAuthenticationContext`.
+
+### Migrating from versions < 21.2.0
+* Stripe3DS2 is now a separate component for Carthage users. You must embed both Stripe.xcframework and Stripe3DS2.xcframework in your app.
+
+### Migrating from versions < 21.0.0
+* The SDK is now written in Swift, and some manual changes are required. Migration instructions are available at [https://stripe.com/docs/mobile/ios/sdk-21-migration](https://stripe.com/docs/mobile/ios/sdk-21-migration).
+
+### Migrating from versions < 20.1.0
+* Swift Package Manager users may need to remove and re-add Stripe from the `Frameworks, Libraries, and Embedded Content` section of your target's settings after updating.
+* Swift Package Manager users with Xcode 12.0 may need to use a [workaround](https://github.com/stripe/stripe-ios/issues/1673) for a code signing issue. This is fixed in Xcode 12.2.
+
+### Migrating from versions < 20.0.0
+* The minimum iOS version is now 11.0. If you'd like to deploy for iOS 10.0, please use Stripe SDK 19.4.0.
+* Card.io is no longer supported. To enable our built-in [card scanning](https://github.com/stripe/stripe-ios#card-scanning) beta, set the `cardScanningEnabled` flag on STPPaymentConfiguration.
+* Catalyst support is out of beta, and now requires Swift Package Manager with Xcode 12 or Cocoapods 1.10.
+
+### Migrating from versions < 19.4.0
+* `metadata` fields are no longer populated on retrieved Stripe API objects and must be fetched on your server using your secret key. If this is causing issues with your deployed app versions please reach out to [Stripe Support](https://support.stripe.com/?contact=true). These fields have been marked as deprecated and will be removed in a future SDK version.
+
+### Migrating from versions < 19.3.0
+* `STPAUBECSFormView` now inherits from `UIView` instead of `UIControl`
+
+### Migrating from versions < 19.2.0
+* The `STPApplePayContext` 'applePayContext:didCreatePaymentMethod:completion:` delegate method now includes paymentInformation: 'applePayContext:didCreatePaymentMethod:paymentInformation:completion:`.
+
+
+### Migrating from versions < 19.0.0
+#### `publishableKey` and `stripeAccount` changes
+* Deprecates `publishableKey` and `stripeAccount` properties of `STPPaymentConfiguration`.
+  * If you used `STPPaymentConfiguration.sharedConfiguration` to set `publishableKey` and/or `stripeAccount`, use `STPAPIClient.sharedClient` instead.
+  * If you passed a STPPaymentConfiguration instance to an SDK component, you should instead create an STPAPIClient, set publishableKey on it, and set the SDK component's APIClient property.
+* The SDK now uses `STPAPIClient.sharedClient` to make API requests by default.
+
+This changes the behavior of the following classes, which previously used API client instances configured from `STPPaymentConfiguration.shared`: `STPCustomerContext`, `STPPaymentOptionsViewController`, `STPAddCardViewController`, `STPPaymentContext`, `STPPinManagementService`, `STPPushProvisioningContext`.
+
+You are affected by this change if:
+
+1. You use `stripeAccount` to work with your Connected accounts
+2. You use one of the above affected classes
+3. You set different `stripeAccount` values on `STPPaymentConfiguration` and `STPAPIClient`, i.e. `STPPaymentConfiguration.shared.stripeAccount != STPAPIClient.shared.stripeAccount`
+
+If all three of the above conditions are true, you must update your integration! The SDK used to send `STPPaymentConfiguration.shared.stripeAccount`, and will now send `STPAPIClient.shared.stripeAccount`.
+
+For example, if you are a Connect user who stores Payment Methods on your platform, but clones PaymentMethods to a connected account and creates direct charges on that connected account i.e. if:
+
+1. You never set `STPPaymentConfiguration.shared.stripeAccount`
+2. You set `STPAPIClient.shared.stripeAccount`
+
+We recommend you do the following:
+
+```
+    // By default, you don't want the SDK to pass stripeAccount
+    STPAPIClient.shared().publishableKey = "pk_platform"
+    STPAPIClient.shared().stripeAccount = nil
+
+    // You do want the SDK to pass stripeAccount when it makes payments directly on your connected account, so
+    // you create a separate APIClient instance...
+    let connectedAccountAPIClient = STPAPIClient(publishableKey: "pk_platform")
+
+    // ...set stripeAccount on it...
+    connectedAccountAPIClient.stripeAccount = "your connected account's id"
+
+    // ...and either set the relevant SDK components' apiClient property to your custom APIClient instance:
+    STPPaymentHandler.shared().apiClient = connectedAccountAPIClient // e.g. if you are using PaymentIntents
+
+    // ...or use it directly to make API requests with `stripeAccount` set:
+    connectedAccountAPIClient.createToken(withCard:...) // e.g. if you are using Tokens + Charges
+```
+#### Postal code changes
+* The user's postal code is now collected by default in countries that support postal codes. We always recommend collecting a postal code to increase card acceptance rates and reduce fraud. To disable this behavior:
+  * For STPPaymentContext and other full-screen UI, set your `STPPaymentConfiguration`'s `.requiredBillingAddressFields` to `STPBillingAddressFieldsNone`.
+  * For a PKPaymentRequest, set `.requiredBillingContactFields` to an empty set. If your app supports iOS 10, also set `.requiredBillingAddressFields` to `PKAddressFieldNone`.
+  * For STPPaymentCardView, set `.postalCodeEntryEnabled` to `NO`.
+* Users may now enter spaces, dashes, and uppercase letters into the postal code field in situations where the user has not explicitly selected a country. This allows users with non-US addreses to enter their postal code.
+* `STPBillingAddressFieldsZip` has been renamed to `STPBillingAddressFieldsPostalCode`.
+#### Localization changes
+* All [Stripe Error messages](https://stripe.com/docs/api/errors#errors-message) are now localized
+  based on the device locale.
+
+  For example, when retrieving a SetupIntent with a nonexistent `id`
+  when the device locale is set to `Locale.JAPAN`, the error message will now be localized.
+  ```
+  // before - English
+  "No such setupintent: seti_invalid123"
+
+  // after - Japanese
+  "そのような setupintent はありません : seti_invalid123"
+  ```
+
+### Migrating from versions < 18.0.0
+* Some error messages from the Payment Intents API are now localized to the user's display language. If your application's logic depends on specific `message` strings from the Stripe API, please use the error [`code`](https://stripe.com/docs/error-codes) instead.
+* `STPPaymentResult` may contain a `paymentMethodParams` instead of a `paymentMethod` when using single-use payment methods such as FPX. Because of this, `STPPaymentResult.paymentMethod` is now nullable. Instead of setting the `paymentMethodId` manually on your `paymentIntentParams`, you may now call `paymentIntentParams.configure(with result: STPPaymentResult)`:
+```
+// 17.0.0
+paymentIntentParams.paymentMethodId = paymentResult.paymentMethod.stripeId
+
+// 18.0.0
+paymentIntentParams.configure(with: paymentResult)
+```
+* `STPPaymentOptionTypeAll` has been renamed to `STPPaymentOptionTypeDefault`. This option will not include FPX or future optional payment methods.
+* The minimum iOS version is now 10.0. If you'd like to deploy for iOS 9.0, please use Stripe SDK 17.0.2.
+
+### Migrating from versions < 17.0.0
+* The API version has been updated from 2015-10-12 to 2019-05-16. CHANGELOG.md has details on the changes made, which includes breaking changes for `STPConnectAccountParams` users. Your backend Stripe API version should be sufficiently decoupled from the SDK's so that keeping their versions in sync is not required, and no further action is required to migrate to this version of the SDK.
+* For STPPaymentContext users: the completion block type in `paymentContext:didCreatePaymentResult:completion:` has changed to `STPPaymentStatusBlock`, to let you inform the context that the user has cancelled.
+
+### Migrating from versions < 16.0.0
+* The following have been migrated from Source/Token to PaymentMethod. If you have integrated with any of these things, you must also migrate to PaymentMethod and the Payment Intent API.  See https://stripe.com/docs/payments/payment-intents/migration.  See CHANGELOG.md for more details.
+  * UI components
+    * STPPaymentCardTextField
+    * STPAddCardViewController
+    * STPPaymentOptionsViewController
+  * PaymentContext
+    * STPPaymentContext
+    * STPCustomerContext
+    * STPBackendAPIAdapter
+    * STPPaymentResult
+  * Standard Integration example project
+* `STPPaymentIntentAction*` types have been renamed to `STPIntentAction*`. Xcode should offer a deprecation warning & fix-it to help you migrate.
+* `STPPaymentHandler` supports 3DS2 authentication, and is recommended instead of `STPRedirectContext`. See https://stripe.com/docs/mobile/ios/authentication
+
+### Migrating from versions < 15.0.0
+* "PaymentMethod" has a new meaning: https://stripe.com/docs/api/payment_methods/object.  All things referring to "PaymentMethod" have been renamed to "PaymentOption" (see CHANGELOG.md for the full list).  `STPPaymentMethod` and `STPPaymentMethodType` have been rewritten to match this new API object.
+* PaymentMethod succeeds Source as the recommended way to charge customers.  In this vein, several 'Source'-named things have been deprecated, and replaced with 'PaymentMethod' equivalents.  For example, `STPPaymentIntentsStatusRequiresSource` is replaced by `STPPaymentIntentsStatusRequiresPaymentMethod` (see CHANGELOG.md for the full list).  Following the deprecation warnings & fix-its will be enough to migrate your code - they've simply been renamed, and will continue to work for Source-based flows.
+
+### Migrating from versions < 14.0.0
+* `STPPaymentCardTextField` now copies the `STPCardParams` object when setting/getting the `cardParams` property, instead of sharing the object with the caller.
+  * Changes to the `STPCardParams` object after setting `cardParams` no longer mutate the object held by the `STPPaymentCardTextField`
+  * Changes to the object returned by `STPPaymentCardTextField.cardParams` no longer mutate the object held by the `STPPaymentCardTextField`
+  * This is a breaking change for code like: `paymentCardTextField.cardParams.name = @"Jane Doe";`
+* `STPPaymentIntentParams.returnUrl` has been renamed to `STPPaymentIntentParams.returnURL`. Xcode should offer a deprecation warning & fix-it to help you migrate.
+* `STPPaymentIntent.returnUrl` has been removed, because it's no longer a property of the PaymentIntent. When the PaymentIntent status is `.requiresSourceAction`, and the `nextSourceAction.type` is `.authorizeWithURL`, you can find the return URL at `nextSourceAction.authorizeWithURL.returnURL`.
+
+### Migrating from versions < 13.1.0
+ * The SDK now supports PaymentIntents with `STPPaymentIntent`, which use `STPRedirectContext` in the same way that `STPSource` does
+   * `STPRedirectContextCompletionBlock` has been renamed to `STPRedirectContextSourceCompletionBlock`. It has the same signature, and Xcode should offer a deprecation warning & fix-it to help you migrate.
+
+### Migrating from versions < 13.0.0
+* Remove Bitcoin source support because Stripe no longer processes Bitcoin payments: https://stripe.com/blog/ending-bitcoin-support
+  * Sources can no longer have a "STPSourceTypeBitcoin" source type. These sources will now be interpreted as "STPSourceTypeUnknown".
+  * You can no longer `createBitcoinParams`. Please use a different payment method.
+
+### Migrating from versions < 12.0.0
+* The SDK now requires iOS 9+ and Xcode version 9+. If you need to support iOS 8 or Xcode 8, the last supported version is [11.5.0](https://github.com/stripe/stripe-ios/releases/tag/v11.5.0)
+* `STPPaymentConfiguration.requiredShippingAddress` now is a set of `STPContactField` objects instead of a `PKAddressField` bitmask.
+  * Most of the previous `PKAddressField` constants have matching `STPContactField` constants. To convert your code, switch to passing in a set of the matching constants
+    * Example: `(PKAddressField)(PKAddressFieldName|PKAddressFieldPostalAddress)` becomes `[NSSet setwithArray:@[STPContactFieldName, STPContactFieldPostalAddress]]`)
+  * Anywhere you were using `PKAddressFieldNone` you can now simply pass in `nil`
+  * If you were using `PKAddressFieldAll`, you must switch to manually listing all the fields that you want.
+  * The new constants also correspond to and work similarly to Apple's new `PKContactField` values.
+* `AddressBook` framework support has been removed. If you were using AddressBook related functionality, you must switch over to using the `Contacts` framework.
+* `STPRedirectContext` will no longer retain itself for the duration of the redirect. If you were relying on this functionality, you must change your code to explicitly maintain a reference to it.
+
+### Migrating from versions < 11.4.0
+* The `STPBackendAPIAdapter` protocol and all associated methods are no longer deprecated. We still recommend using `STPCustomerContext` to update a Stripe customer object on your behalf, rather than using your own implementation of `STPBackendAPIAdapter`.
+
+### Migrating from versions < 11.3.0
+* Changes to  `STPCard`, `STPCardParams`, `STPBankAccount`, and `STPBankAccountParams`
+  * `STPCard` no longer subclasses from `STPCardParams`. You must now specifically create `STPCardParams` objects to create new tokens.
+  * `STPBankAccount` no longer subclasses from `STPBankAccountParams`.
+  * You can no longer directly create `STPCard` objects, you should only use ones that have been decoded from Stripe API responses via `STPAPIClient`.
+  * All `STPCard` and `STPBankAccount` properties have been made readonly.
+  * Broken out individual address properties on `STPCard` and `STPCardParams` have been deprecated in favor of the grouped `address` property.
+* The value of `[STPAPIResponseDecodable allResponseFields]` is now completely (deeply) filtered to not contain any instances of `[NSNull null]`. Previously, only `[NSNull null]` one level deep (shallow) were removed.
+
+### Migrating from versions < 11.2.0
+* `STPCustomer`'s `shippingAddress` property is now correctly annotated as nullable. Its type is an optional (`STPAddress?`) in Swift.
+
+### Migrating from versions < 11.0.0
+- We've greatly simplified the integration for `STPPaymentContext`. In order to migrate to the new `STPPaymentContext` integration using ephemeral keys, you'll need to:
+  1. On your backend, add a new endpoint that creates an ephemeral key for the Stripe customer associated with your user, and returns its raw JSON. Note that you should _not_ remove the 3 endpoints you added for your initial PaymentContext integration until you're ready to drop support for previous versions of your app.
+  2. In your app, make your API client class conform to `STPEphemeralKeyProvider` by adding a method that requests an ephemeral key from the endpoint you added in (1).
+  3. In your app, remove any references to `STPBackendAPIAdapter`. Your API client class will no longer need to conform to `STPBackendAPIAdapter`, and you can delete the `retrieveCustomer`, `attachSourceToCustomer`, and `selectDefaultCustomerSource` methods.
+  4. Instead of using the initializers for `STPPaymentContext` or `STPPaymentMethodsViewController` that take an `STPBackendAPIAdapter` parameter, you should use the new initializers that take an `STPCustomerContext` parameter. You'll need to set up your instance of `STPCustomerContext` using the key provider you set up in (2).
+- For a more detailed overview of the new integration, you can refer to our tutorial at https://stripe.com/docs/mobile/ios/standard
+- `[STPFile stringFromPurpose:]` now returns `nil` for `STPFilePurposeUnknown`. Will return a non-nil value for all other `STPFilePurpose`.
+- We've removed the `email` and `phone` properties in `STPUserInformation`. You can pre-fill this information in the shipping form using the new `shippingAddress` property.
+- The SMS card fill feature has been removed from `STPPaymentContext`, as well as the associated `smsAutofillDisabled` configuration option (ie it will now always behave as if it is disabled).
+
+### Migrating from versions < 10.2.0
+- `paymentRequestWithMerchantIdentifier:` has been deprecated. You should instead use `paymentRequestWithMerchantIdentifier:country:currency:`. Apple Pay is now available in many countries and currencies, and you should use the appropriate values for your business.
+- We've added a `paymentCountry` property to `STPPaymentContext`. This affects the countryCode of Apple Pay payments, and defaults to "US". You should set this to the country your Stripe account is in.
+- Polling for source object updates is deprecated. Check https://stripe.com/docs for the latest best practices on how to integrate with the sources API using webhooks.
+- `paymentMethodsViewController:didSelectPaymentMethod:` is now optional. If you have an empty implementation of this method, you can remove it.
+
+### Migrating from versions < 10.1.0
+
+- STPPaymentMethodsViewControllerDelegate now has a separate `paymentMethodsViewControllerDidCancel:` callback, differentiating from successful method selections. You should make sure to also dismiss the view controller in that callback.
+
+### Migrating from versions < 10.0
+
+- Methods deprecated in Version 6.0 have now been removed.
+- The `STPSource` protocol has been renamed `STPSourceProtocol`.
+- `STPSource` is now a model object representing a source from the Stripe API. https://stripe.com/docs/sources
+- `STPCustomer` will now include `STPSource` objects in its `sources` array if a customer has attached sources.
+- `STPErrorCode` and `STPCardErrorCode` are now first class Swift enums (before, their types were `Int` and `String`, respectively)
+
+### Migrating from versions < 9.0
+
+Version 9.0 drops support for iOS 7.x and Xcode 7.x. If you need to support iOS or Xcode versions below 8.0, the last compatible Stripe SDK release is version 8.0.7.
+
+### Migrating from versions < 6.0
+
+6.0 moves most of the contents of `STPCard` into a new class, `STPCardParams`, which represents a request to the Stripe API. `STPCard` now only refers to responses from the Stripe API. Most apps should be able to simply replace all usage of `STPCard` with `STPCardParams` - you should only use `STPCard` if you're dealing with an API response, e.g. a card attached to an `STPToken`. This renaming has been done in a way that will avoid breaking changes, although using `STPCard`s to make requests to the Stripe API will produce deprecation warnings.
+
+### Migrating from versions < 5.0
+
+5.0 deprecates our native Stripe Checkout adapters. If you were using these, we recommend building your own credit card form instead. If you need help with this, please contact support@stripe.com.
+
+### Migrating from versions < 3.0
+
+Before version 3.0, most token-creation methods were class methods on the `Stripe` class. These are now all instance methods on the `STPAPIClient` class. Where previously you might write
+```objective-c
+[Stripe createTokenWithCard:card publishableKey:myPublishableKey completion:completion];
+```
+you would now instead write
+```objective-c
+STPAPIClient *client = [[STPAPIClient alloc] initWithPublishableKey:myPublishableKey];
+[client createTokenWithCard:card completion:completion];
+```
+This version also made several helper classes, including `STPAPIConnection` and `STPUtils`, private. You should remove any references to them from your code (most apps shouldn't have any).
+
+## Migrating from versions < 1.2
+
+Versions of Stripe-iOS prior to 1.2 included a class called `STPView`, which provided a pre-built credit card form. This functionality has been moved from Stripe-iOS to PaymentKit, a separate project. If you were using `STPView` prior to version 1.2, migrating is simple:
+
+1. Add PaymentKit to your project, as explained on its [project page](https://github.com/stripe/PaymentKit).
+2. Replace any references to `STPView` with a `PTKView` instead. Similarly, any classes that implement `STPViewDelegate` should now instead implement the equivalent `PTKViewDelegate` methods. Note that unlike `STPView`, `PTKView` does not take a Stripe API key in its constructor.
+3. To submit the credit card details from your `PTKView` instance, where you would previously call `createToken` on your `STPView`, replace that with the following code (assuming `self.paymentView` is your `PTKView` instance):
+
+```objective-c
+if (![self.paymentView isValid]) {
+    return;
+}
+STPCard *card = [[STPCard alloc] init];
+card.number = self.paymentView.card.number;
+card.expMonth = self.paymentView.card.expMonth;
+card.expYear = self.paymentView.card.expYear;
+card.cvc = self.paymentView.card.cvc;
+STPAPIClient *client = [[STPAPIClient alloc] initWithPublishableKey:publishableKey];
+[client createTokenWithCard:card completion:^(STPToken *token, NSError *error) {
+    if (error) {
+        // handle the error as you did previously
+    } else {
+        // submit the token to your payment backend as you did previously
+    }
+}];
+```
+
+## Misc. notes
+
+### Handling errors
+
+See [StripeError.h](https://github.com/stripe/stripe-ios/blob/master/Stripe/PublicHeaders/Stripe/StripeError.h) for a list of error codes that may be returned from the Stripe API.
+
+### Validating STPCards
+
+You have a few options for handling validation of credit card data on the client, depending on what your application does.  Client-side validation of credit card data is not required since our API will correctly reject invalid card information, but can be useful to validate information as soon as a user enters it, or simply to save a network request.
+
+The simplest thing you can do is to populate an `STPCard` object and, before sending the request, call `- (BOOL)validateCardReturningError:` on the card.  This validates the entire card object, but is not useful for validating card properties one at a time.
+
+To validate `STPCard` properties individually, you should use the following:
+
+```objective-c
+ - (BOOL)validateNumber:error:
+ - (BOOL)validateCvc:error:
+ - (BOOL)validateExpMonth:error:
+ - (BOOL)validateExpYear:error:
+```
+
+These methods follow the validation method convention used by [key-value validation](http://developer.apple.com/library/mac/#documentation/cocoa/conceptual/KeyValueCoding/Articles/Validation.html).  So, you can use these methods by invoking them directly, or by calling `[card validateValue:forKey:error]` for a property on the `STPCard` object.
+
+When using these validation methods, you will want to set the property on your card object when a property does validate before validating the next property.  This allows the methods to use existing properties on the card correctly to validate a new property.  For example, validating `5` for the `expMonth` property will return YES if no `expYear` is set.  But if `expYear` is set and you try to set `expMonth` to 5 and the combination of `expMonth` and `expYear` is in the past, `5` will not validate.  The order in which you call the validate methods does not matter for this though.

+
+## Features
+
+**Simplified security**: We make it simple for you to collect sensitive data such as credit card numbers and remain [PCI compliant](https://stripe.com/docs/security#pci-dss-guidelines). This means the sensitive data is sent directly to Stripe instead of passing through your server. For more information, see our [integration security guide](https://stripe.com/docs/security).
+
+**Apple Pay**: [StripeApplePay](StripeApplePay/README.md) provides a [seamless integration with Apple Pay](https://stripe.com/docs/apple-pay).
+
+**SCA-ready**: The SDK automatically performs native [3D Secure authentication](https://stripe.com/docs/payments/3d-secure) if needed to comply with [Strong Customer Authentication](https://stripe.com/docs/strong-customer-authentication) regulation in Europe.
+
+**Native UI**: We provide native screens and elements to collect payment details. For example, [PaymentSheet](https://stripe.com/docs/payments/accept-a-payment?platform=ios) is a prebuilt UI that combines all the steps required to pay - collecting payment details, billing details, and confirming the payment - into a single sheet that displays on top of your app.
+
+<img src="https://user-images.githubusercontent.com/89988962/153276097-9b3369a0-e732-45c4-96ec-ff9d48ad0fb6.png" alt="PaymentSheet" align="center"/>
+
+**Stripe API**: [StripePayments](StripePayments/README.md) provides [low-level APIs](https://stripe.dev/stripe-ios/docs/Classes/STPAPIClient.html) that correspond to objects and methods in the Stripe API. You can build your own entirely custom UI on top of this layer, while still taking advantage of utilities like [STPCardValidator](https://stripe.dev/stripe-ios/docs/Classes/STPCardValidator.html) to validate your user’s input.
+
+**Card scanning**: We support card scanning on iOS 13 and higher. See our [Card scanning](#card-scanning) section.
+
+**App Clips**: The `StripeApplePay` module provides a [lightweight SDK for offering Apple Pay in an App Clip](https://stripe.com/docs/apple-pay#app-clips).
+
+**Localized**: We support the following localizations: Bulgarian, Catalan, Chinese (Hong Kong), Chinese (Simplified), Chinese (Traditional), Croatian, Czech, Danish, Dutch, English (US), English (United Kingdom), Estonian, Filipino, Finnish, French, French (Canada), German, Greek, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Malay, Maltese, Norwegian Bokmål, Norwegian Nynorsk (Norway), Polish, Portuguese, Portuguese (Brazil), Romanian, Russian, Slovak, Slovenian, Spanish, Spanish (Latin America), Swedish, Turkish, Thai and Vietnamese.
+
+#### Recommended usage
+
+If you're selling digital products or services that will be consumed within your app, (e.g. subscriptions, in-game currencies, game levels, access to premium content, or unlocking a full version), you must use Apple's in-app purchase APIs. See the [App Store review guidelines](https://developer.apple.com/app-store/review/guidelines/#payments) for more information. For all other scenarios you can use this SDK to process payments via Stripe.
+
+#### Privacy
+
+The Stripe iOS SDK collects data to help us improve our products and prevent fraud. This data is never used for advertising and is not rented, sold, or given to advertisers. Our full privacy policy is available at [https://stripe.com/privacy](https://stripe.com/privacy).
+
+For help with Apple's App Privacy Details form in App Store Connect, visit [Stripe iOS SDK Privacy Details](https://support.stripe.com/questions/stripe-ios-sdk-privacy-details).

For iOS 10, please use [v19.4.0](https://github.com/stripe/stripe-ios/tree/v19.4.0). If you need to support iOS 9, use [v17.0.2](https://github.com/stripe/stripe-ios/tree/v17.0.2).
+
+## Getting started
+
+### Integration
+
+Get started with our [📚 integration guides](https://stripe.com/docs/payments/accept-a-payment?platform=ios) and [example projects](/Example), or [📘 browse the SDK reference](https://stripe.dev/stripe-ios/docs/index.html) for fine-grained documentation of all the classes and methods in the SDK.
+
+### Examples
+
+- [Prebuilt UI](Example/PaymentSheet%20Example) (Recommended)
+  - This example demonstrates how to build a payment flow using [`PaymentSheet`](https://stripe.com/docs/payments/accept-a-payment?platform=ios), an embeddable native UI component that lets you accept [10+ payment methods](https://stripe.com/docs/payments/payment-methods/integration-options#payment-method-product-support) with a single integration.
+
+- [Non-Card Payment Examples](Example/Non-Card%20Payment%20Examples)
+  - This example demonstrates how to manually accept various payment methods using the Stripe API.
+
+### Building from source
+
+We use [Tuist](https://tuist.io) to generate Xcode projects, and all Xcode related files have been removed from the master branch of the repository. Note that project files are still available on tagged releases.
+
+If you want to build from the master branch you need to follow these steps:
+
+- Clone the repository and `cd` into its directory.
+- Install Tuist by following the instructions at [tuist.io](https://docs.tuist.io/tutorial/get-started/).
+- Run `tuist generate`, optionally pass the `-n` option if you don't want to open Xcode automatically.
+
+You can build any of the generated targets as you normally would.
+
+For more information about Tuist, visit https://tuist.io.
+
+## Card scanning
+
+[PaymentSheet](https://stripe.com/docs/payments/accept-a-payment?platform=ios) offers built-in card scanning. To enable card scanning, you'll need to set `NSCameraUsageDescription` in your application's plist, and provide a reason for accessing the camera (e.g. "To scan cards"). Card scanning is supported on devices with iOS 13 or higher.
+
+You can demo this feature in our [PaymentSheet example app](Example/PaymentSheet%20Example). When you run the example app on a device, you'll see a "Scan Card" button when adding a new card.
+
+## Contributing
+
+We welcome contributions of any kind including new features, bug fixes, and documentation improvements. Please first open an issue describing what you want to build if it is a major change so that we can discuss how to move forward. Otherwise, go ahead and open a pull request for minor changes such as typo fixes and one liners.
+
+### Running tests
+
+1. Install Carthage 0.37 or later (if you have homebrew installed, `brew install carthage`)
+2. From the root of the repo, run `bundle install && bundle exec fastlane stripeios_tests`. This will install the test dependencies and run the tests.
+3. Once you have run this once, you can also run the tests in Xcode from the `StripeiOS` target in `Stripe.xcworkspace`. Make sure to use the iPhone 12 mini, iOS 16.1 simulator so the snapshot tests will pass.
+
+## Migrating from older versions
+
+See [MIGRATING.md](https://github.com/stripe/stripe-ios/blob/master/MIGRATING.md)
+
+## Code style
+We use [swiftlint](https://github.com/realm/SwiftLint) to enforce code style.
+
+To install it, run `brew install swiftlint`
+
+To lint your code before pushing you can run `ci_scripts/lint_modified_files.sh`
+
+You can also add this script as a pre-push hook by running `ln -s "$(pwd)/ci_scripts/lint_modified_files.sh" .git/hooks/pre-push && chmod +x .git/hooks/pre-push`
+
+To format modified files automatically, you can use `ci_scripts/format_modified_files.sh` and you can add it as a pre-commit hook using `ln -s "$(pwd)/ci_scripts/format_modified_files.sh" .git/hooks/pre-commit && chmod +x .git/hooks/pre-commit`

That class is restricted to apps with a special entitlement from Apple, and as such can be difficult to build and test against. This class implements the same public API as `PKAddPaymentPassViewController`, and can be used to develop against the Stripe API in *testmode only*. (Obviously it will not actually place cards into the user's Apple Pay wallet either.) When it's time to go to production, you may simply replace all references to `STPFakeAddPaymentPassViewController` in your app with `PKAddPaymentPassViewController` and it will continue to function.

+# Stripe CardScan iOS SDK
+
+This library provides support for the standalone Stripe CardScan product.
+
+## Overview
+
+This library provides a user interface through which users can scan payment cards and extract information from them. It uses the Stripe Publishable Key to authenticate with Stripe services.
+
+Note that this is a standalone SDK and, while compatible with, does not directly integrate with the [PaymentIntent](https://stripe.com/docs/api/payment_intents) API nor with [next_action](https://stripe.com/docs/api/errors#errors-payment_intent-next_action).
+
+This library can be used entirely outside of a Stripe integration and with other payment processing providers.
+
+## Requirements
+
+- iOS 13.0 or higher
+- XCode 14.1 or higher
+
+## Example
+
+See the [CardImageVerification Example](https://github.com/stripe/stripe-ios/tree/master/Example/CardImageVerification%20Example) directory for an example application that you can try for yourself!
+
+## Installation
+
+- Cocoapod
+    - `pod install StripeCardScan`
+- SPM
+    - In Xcode, select File > Add Packages… and enter https://github.com/stripe/stripe-ios-spm as the repository URL.
+    - Select the latest version number from our releases page.
+    - Add the `StripeCardScan` product to the target of your app.
+
+## Integration
+### Credit Card OCR
+Add `CardScanSheet` in your view controller where you want to invoke the credit card scanning flow.
+
+1. Set up camera permissions
+    * The SDK uses the camera, so you'll need to add an description of camera usage to your Info.plist file:
+![info.plist camera permissions](https://gblobscdn.gitbook.com/assets%2F-MAfqrnL3d-uke0sAFsI%2Fsync%2F573e3f05043e4d903189b5fb107d4b3565bdb11b.png?alt=media)
+![camera permissions prompt](https://gblobscdn.gitbook.com/assets%2F-MAfqrnL3d-uke0sAFsI%2Fsync%2F0d7119d3cbe2f519e5e5c04b56fe43539e4435e1.png?alt=media)
+
+    * Alternatively, you can add this permission directly to your Info.plist file:
+    ```
+    <key>NSCameraUsageDescriptionkey>
+    <string>We need access to your camera to scan your cardstring>
+    ```
+2. Add `CardScanSheet` in your app where you want to invoke the scan flow
+    * Initialize `CardScanSheet`
+    * When it’s time to invoke the scan flow, display the sheet with `CardScanSheet.present()`
+    * When the verification flow is finished, the sheet will be dismissed and the completion block will be called with a [Result](https://stripe.dev/stripe-ios/)
+
+### Example Implementation
+```swift
+
+import UIKit
+import StripeCardScan
+
+class ViewController: UIViewController {
+
+    @IBAction func cardScanSheetButtonPressed() {
+        let cardScanSheet = CardScanSheet()
+
+        cardScanSheet.present(from: self) { [weak self] result in
+            switch result {
+                case .completed(let scannedCard):
+                /*
+                 * The user scanned a card. The result of the scan are detailed 
+                 * in the `scannedCard` field of the result.
+                 */
+                print("scan success")
+            case .canceled:
+                /*
+                * The scan was canceled by the user.
+                */
+                print("scan canceled")
+            case .failed(let error):
+                 /*
+                 * The scan failed. The displayable error is
+                 * included in the `localizedDescription`. 
+                 */
+                 print("scan failed: \(error.localizedDescription)")
+            }
+        }
+    }
+}
+```

+/// This is the main loop for OCR. It runs one of our OCR systems in paralell with the Apple OCR system and
+/// combines results. From a high level this implements a standard producer-consumer where the main
+/// system will push images and ROI rectangles into the main loop and two Analyzers, or OCR systems
+/// will consume the images.
+///
+/// The producer, which pushes images will keep N (2 currently) images in the queue and when a new image
+/// comes in it will remove old images leaving the N most recent images. That way we can try to get more
+/// diversity in images by virtue of maximizing the time in between images that it reads.
+///
+/// The consumers pull images from the queue and run the full OCR algorithm, including expiry extraction and
+/// full error correction on the combined results.
+///
+/// In terms of iOS abstractions, we make heavy use of dispatch queues. We have a single `mutexQueue`
+/// that we use to mutate our shared state. This queue is a serial queue and our method for synchronizing
+/// access. One thing to be careful with is we use `sync` in places to access our `mutexQueue`. This
+/// method can lead to deadlock if you aren't careful.
+///
+/// # Correcness criteria
+/// We make heavy use of dispatch queues for paralellism, so it's important to be disciplined about how
+/// we access shared state
+///
+/// ## Shared state
+/// All shared state updates need to happeon on the `mutexQueue` except for `machineLearningQueue`,
+/// which we set at the constructor and access it read only.
+///
+/// ## Delegate invocation
+/// All invocations of delegate methods need to happen on the main queue, and for each prediction there
+/// are one or more methods that may get called in order:
+/// - `prediction` this happens on all predictions
+/// - if the scan predicts a number, then `showCardDetails` happens with the current overall predicted number, expiry, and name
+/// - if the scan is complete, then `complete` includes the final result
+///
+/// To finalize results, we clear out the `mainLoopDelegate` after it's done
+///
+/// It's important that we not update `scanStats` after complete is called or call any futher delegate functions, although
+/// more predictions might come through after the fact
+///
+/// We also expose `shouldUsePrediction` that delegates can implement to discard a prediction, but note that the `prediction`
+/// method still fires even when this returns false. Note: `shouldUsePrediction` is called from the `mutexQueue` so handlers
+/// don't need to synchronize but they may need to handle any computation that needs to happen on the main loop appropriately.
+///
+/// ## userCancelled
+/// One aspect to be careful with when someone invokes the `userCancelled` method is that there could be a race with OCR and it
+/// could complete OCR in parallel with this call. The net result we want is if a caller calls this method we don't subsequenty fire any of
+/// the `OcrMainLoopDelegate` methods and we want to make sure that `scanStats.success` is always `false` to correctly
+/// denote that this scan failed.
+///
+/// To handle this correctly we:
+/// - use the `userDidCancel` variable here and in any of our blocks that run on the main dispatch queue. Since this call should
+/// come from the main dispatch queue, those calls, where we invoke the callback methods, will run after this one and we prevent firing
+/// their delegate methods.
+/// - the logic to set `scanStats.success` will come on the `muxtexQueue`, but could execute either before or after this block runs.
+///    - If it's before then this block will overwrite the `success` results with the unsuccessful result here. If the
+///    - If it runs after, there is a check and it sets `scanStats.success` iff it isn't already set
+/// - we use `sync` on the `muxtexQueue` to make sure that when this method returns any subsequent calls to `scanStats` are
+/// always `success = false`
+///
+/// ## backgrounding
+/// We track when the app is in the active state and stop accepting images when it's inactive. When it becomes active we reset
+/// the `errorCorrection` state before re-enabling computation.
+///
+/// This backgrounding logic is less about correctness and more about making sure that the SDK doesn't send the caller predictions
+/// at unexpected times by making sure that the app is active if and when it sends notifications of success.

+/// # Backgrounding and ML
+/// Our ML algorithms use the GPU and can cause crashes when we run them in the background. Thus, we track the app's
+/// backgrounding state and stop any tasks before the app reaches the background.
+///
+/// # Correctness criteria
+/// We have three different functions: `async`, `willResignActive`, and `didBecomeActive` that all run on the main dispatch
+/// queue. In terms of ordering constraints:
+///  - The system enforces state transitions such that each time you resign active it'll be paired with a `didBecomeActive` call
+///    and vice versa.
+///
+/// Given this constraint, you can expect a few different interleavings
+///  - async, resign, become
+///  - async, become, resign
+///  - become, async, resign
+///  - become, resign, async
+///  - resign, async, become
+///  - resign, become, async
+///
+/// In general, we maintain two states: the system's notion of our app's application state and our own notion of active that is a
+/// subset of the more general active system state. In other words, if our app is inactive then our own internal `isActive` is
+/// always false, but if the app is active our internal `isActive` may be false or it may be true. However, if it is `false`
+/// we know that we'll get a become event soon.
+///
+/// Our correctness criterai is that our work items run iff the app is in the active state and each of them runs to completion
+/// in the same order that they were posted (same semantics as a serial dispatch queue).
+///
+/// The only time that computation can run is in between calls to `become` and `resign` because of our internal `isActive` variable.
+/// After the system calls resign, then all work items are added to the `pendingComputations` list in order, which are then posted to the `queue` in order on the `become` call before releasing the main queue. Subsequent calls to `async` will post to the `queue` but
+/// because the posting happens in the main queue, we can ensure correct execution ordering.

+// This class is all programmatic UI with a small bit of logic to handle
+// the events that ScanBaseViewController expects subclasses to implement.
+// Our goal is to have a fully featured Card Scan implementation with a
+// minimal UI that people can customize fully. You can use this directly or
+// you can subclass and customize it. If you'd like to use an off-the-shelf
+// design as well, we suggest using the `ScanViewController`, which uses
+// mature and well tested UI design patterns.
+//
+// The default UI looks something like this, with most of the constraints
+// shown:

+// For the UI we separate out the key components into three parts:
+// - Five `*String` variables that we use to set the copy
+// - For each component or group of components we have:
+//   - `setup*Ui` functions for setting the visual look and feel
+//   - `setup*Constraints for setting up autolayout
+// - We have top level `setupUiComponents` and `setupConstraints` functions that do
+//   a small bit of setup and call the appropriate setup functions for each
+//   components
+//
+// And to customize the UI you can either override any of these functions or you
+// can access components directly to adjust. Also, you're welcome to copy and paste
+// this code and customize it to fit your needs -- we're fine with whatever makes
+// the most sense for your app.

+/// This is our completion loop buffer.

+/// In general, our goal is to capture frames that will work best with our fraud models while capturing fraud behavior. As such:
+///  1. We give top priority to frames where the UX model finds a card _and_ we perform OCR on the frame successfully
+///  2. Next priority goes to frames that the UX model finds a card but it could _not_ perform OCR on the frame
+///  3. Lowest priority goes to frames that pass OCR but _not_ the UX model
+///
+/// One consequence of this priority is that even if we perform OCR successfully we could end up with all frames _without_

+///
+/// We can assume that any frames that pass OCR will be recent (within the last 2-3 seconds). This is _always_ true for

+Data retrieved through Financial Connections can help you unlock a variety of use cases, including:
+
+- Tokenized account and routing numbers let you instantly verify bank accounts for ACH Direct Debit payments.
+- Real-time balance data helps you avoid fees from insufficient funds failures before initiating a bank-based payment or wallet transfer.
+- Account ownership information, such as the name and address of the bank accountholder, helps you mitigate fraud when onboarding a customer or merchant.
+- Transactions data that you can use to help users track expenses, handle bills, manage their finances, and take control of their financial well-being.
+- Transactions and balance data helps you speed up underwriting and improve access to credit and other financial services.
+
+
+

+# <img src="../readme-images/Identity-light-80x80.png" width="40" /> Stripe Identity iOS SDK
+
+The Stripe Identity iOS SDK makes it quick and easy to verify your user's identity in your iOS app. We provide a prebuilt UI to collect your user's ID documents, match photo ID with selfies, and validate ID numbers.
+
+> To get access to the Identity iOS SDK, visit the [Identity Settings](https://dashboard.stripe.com/settings/identity) page and click **Enable**.
+

+   * [Integration](#integration)
+   * [Example](#example)
+* [Manual linking](#manual-linking)
+
+<!--te-->
+
+## Features
+
+**Simplified security**: We've made it simple for you to securely collect your user's personally identifiable information (PII) such as identity document images. Sensitive PII data is sent directly to Stripe Identity instead of passing through your server. For more information, see our [integration security guide](https://stripe.com/docs/security).
+
+**Automatic document capture**: We automatically capture images of the front and back of government-issued photo ID to ensure a clear and readable image.
+
+**Selfie matching**: We capture photos of your user's face and review it to confirm that the photo ID belongs to them. For more information, see our guide on [adding selfie checks](https://stripe.com/docs/identity/selfie).
+
+**Identity information collection**: We collect name, date of birth, and government ID number to validate that it is real.
+
+**Prebuilt UI**: We provide [`IdentityVerificationSheet`](https://stripe.dev/stripe-ios/stripe-identity/Classes/IdentityVerificationSheet.html), a prebuilt UI that combines all the steps required to collect ID documents, selfies, and ID numbers into a single sheet that displays on top of your app.
+
+**Automated verification**: Stripe Identity's automated verification technology looks for patterns to help determine if an ID document is real or fake and uses distinctive physiological characteristics of faces to match your users' selfies to photos on their ID document. Collected identity information is checked against a global set of databases to confirm that it exists. Learn more about the [verification checks supported by Stripe Identity](https://stripe.com/docs/identity/verification-checks), [accessing verification results](https://stripe.com/docs/identity/access-verification-results), or our integration guide on [handling verification outcomes](https://stripe.com/docs/identity/handle-verification-outcomes).
+
+## Requirements
+
+The Stripe Identity iOS SDK is compatible with apps targeting iOS 13.0 or above.
+
+If you intend to use this SDK with Stripe's Identity service, you must not modify this SDK. Using a modified version of this SDK with Stripe's Identity service, without Stripe's written authorization, is a breach of your agreement with Stripe and may result in your Stripe account being shut down.
+
+
+## Getting started
+
+### Integration
+
+Get started with Stripe Identity's [📚 iOS integration guide](https://stripe.com/docs/identity/verify-identity-documents?platform=ios) and [example project](../Example/IdentityVerification%20Example), or [📘 browse the SDK reference](https://stripe.dev/stripe-ios/stripe-identity/index.html) for fine-grained documentation of all the classes and methods in the SDK.
+
+> Identity SDK uses camera to scan documents and selfies, you'll need to set `NSCameraUsageDescription` in your application's plist, and provide a reason for accessing the camera (e.g. "This app uses the camera to take a picture of your identity documents.").
+
+### Example
+
+[Identity Verification Example](../Example/IdentityVerification%20Example) – This example demonstrates how to capture your users' ID documents on iOS and securely send them to Stripe Identity for identity verification.
+
+## Manual linking
+
+If you link the Stripe Identity library manually, use a version from our [releases](https://github.com/stripe/stripe-ios/releases) page and make sure to embed <ins>all</ins> of the following frameworks:
+- `StripeIdentity.xcframework`
+- `StripeCore.xcframework`
+- `StripeCameraCore.xcframework`
+- `StripeUICore.xcframework`

+# StripePaymentSheet iOS SDK module
+
+PaymentSheet is a prebuilt UI that combines all the steps required to pay - collecting payment details, billing details, and confirming the payment - into a single sheet that displays on top of your app.
+
+## Table of contents

+* [Features](#features)
+* [Requirements](#requirements)
+* [Getting started](#getting-started)
+   * [Integration](#integration)
+   * [Example](#example)
+* [Manual linking](#manual-linking)
+
+<!--te-->
+
+## Requirements
+
+The StripePaymentSheet module is compatible with apps targeting iOS 13.0 or above.
+
+## Getting started
+
+### Integration
+
+Get started with our [📚 integration guides](https://stripe.com/docs/payments/accept-a-payment?platform=ios&ui=payment-sheet) and [example projects](/Example), or [📘 browse the SDK reference](https://stripe.dev/stripe-ios/stripe-paymentsheet/index.html) for fine-grained documentation of all the classes and methods in the SDK.
+
+### Example
+
+- [Prebuilt UI](Example/PaymentSheet%20Example)
+  - This example demonstrates how to build a payment flow using [`PaymentSheet`](https://stripe.com/docs/payments/accept-a-payment?platform=ios), an embeddable native UI component that lets you accept [10+ payment methods](https://stripe.com/docs/payments/payment-methods/integration-options#payment-method-product-support) with a single integration.
+
+## Manual linking
+
+If you link this library manually, use a version from our [releases](https://github.com/stripe/stripe-ios/releases) page and make sure to embed <ins>all</ins> of the following frameworks:
+- `StripeCore.xcframework`
+- `StripeUICore.xcframework`
+- `Stripe3DS2.xcframework`
+- `StripePayments.xcframework`
+- `StripePaymentsUI.xcframework`
+- `StripeApplePay.xcframework`
+- `StripePaymentSheet.xcframework`

+# StripePaymentsUI iOS SDK module
+
+The StripePaymentsUI module contains UI elements and API bindings for building a custom payment flow using Stripe.
+
+It contains:
+
+* [STPPaymentCardTextField](https://stripe.dev/stripe-ios/stripe-payments-ui/Classes/STPPaymentCardTextField.html), a single-line interface for users to input their credit card details.
+* [STPCardFormView](https://stripe.dev/stripe-ios/stripe-payments-ui/Classes/STPCardFormView.html), a multi-line interface for users to input their credit card details.
+* [STPAUBECSDebitFormView](https://stripe.dev/stripe-ios/stripe-payments-ui/Classes/STPAUBECSDebitFormView.html), a UIControl that contains all of the necessary fields and legal text for collecting AU BECS Debit payments.

+
+## Requirements
+
+The StripePaymentsUI module is compatible with apps targeting iOS 13.0 or above.
+
+## Getting started
+
+### Integration
+
+Get started with our [📚 integration guides](https://stripe.com/docs/payments/accept-a-payment?platform=ios&ui=custom) and [example projects](/Example), or [📘 browse the SDK reference](https://stripe.dev/stripe-ios/stripe-payments-ui/index.html) for fine-grained documentation of all the classes and methods in the SDK.
+
+### Example
+
+- [Accept a Payment Example](https://github.com/stripe-samples/accept-a-payment/tree/main/custom-payment-flow/client/ios-swiftui)
+   – This example demonstrates how to collect payment information on iOS using `STPPaymentCardTextField`.
+
+## Manual linking
+
+If you link this library manually, use a version from our [releases](https://github.com/stripe/stripe-ios/releases) page and make sure to embed <ins>all</ins> of the following frameworks:
+- `StripeCore.xcframework`
+- `StripeUICore.xcframework`
+- `Stripe3DS2.xcframework`
+- `StripePayments.xcframework`
+- `StripePaymentsUI.xcframework`
