CurrencyConverter is a Swift-based iOS application designed to seamlessly convert amounts between different currencies. Built using UIKit and Core Data, this app fetches real-time currency rates from Open Exchange Rates and stores them locally for quick access and offline usage.
- Real-Time Conversion: Convert any amount between multiple currencies with ease.
- Automatic Updates: Currency rates are fetched and updated every 30 minutes to ensure accuracy.
- Offline Mode: Currency rates are stored locally using Core Data, allowing conversions even without an internet connection.
- Unit Tested: Comprehensive unit tests ensure reliability and accuracy of currency conversions.
- MVVM Architecture: The project follows the Model-View-ViewModel (MVVM) architecture, promoting a clean, maintainable, and scalable codebase.
- Best Practices: Adheres to industry best practices, with a focus on decoupled design for easier maintenance and scalability.
CurrencyConverter integrates with the Open Exchange Rates API to obtain the latest exchange rates. The API endpoint used is:
GET https://openexchangerates.org/api/latest.json
To use this API, you need to create a free account on Open Exchange Rates and obtain your appid.
To run this project, you will need to create Config.xcconfig and add it to the Configurations folder. Then, add the APP_ID variable with the value you obtained in the previous step.
