Importing Build error

[bevice1]

Hi, when i use the Swift Package Manager to import your Library. I get a build error "cannot find type 'ResponseType' in scope".
If I clone the repo and import it as a local library, there are no build errors but none of your examples work. Despite importing LibP2PKadDHT it cannot find classes like BasicKadDHT.

XCode Version 15.0 (15A240d)
iOS 17

How is your package supposed to be used in a project? I saw the installation guide but thats only for importing to another package.

Kind regards

Hey @bevice1,

It looks like I forgot to tag the latest commits to the swift-libp2p-kad-dht repo. Swifts package manager picks up the last tagged commit by default instead of the just the main branch. It's tagged now, so it should work.

In your project, if you right click on swift-libp2p-kad-dht in the dependencies on your left hand column and click update package it should updated to 0.1.0 and then build without errors.

As for using the swift-libp2p suite in an iOS / macOS project you can reference the iOS Chat App Example to get some ideas on how to start. In that example I create a Libp2p Service Singleton where I configure and manage the libp2p service (installing mplex, noise, and in that example mdns, but you can swap that for kadDHT). You can then pass the libp2p service to your various views throughout the project using dependency injection or as an environment variable in SwiftUI.

The Kad DHT package is in a pretty rough place at the moment. I was just testing it and noticed that peer discovery events don't get published correctly. So I'll try and set aside some time this week to tidy some things up and hopefully get the peer discovery portion working correctly.

Let me know if you have any more issues / questions, I'm happy to help.

Hi, it works!
I have been playing around with the iOS Chat App example for a bit. And i discovered the an error at the peer discovery:

Is this the bug you were talking about?

Do you have any ideas how to fix this?
