I'm trying to define my AppDelegate instance in the iosMain section of my shared module so that I can create background tasks when authenticating using PKCE. I specify the instance from the shared module using "@UIApplicationDelegateAdaptor" in my SwiftUI main app. I'm getting this error when I compile. Anybody know how to work around this error? I only implemented the didFinishLaunchingWithOptions method.

When two Swift methods have the same 'name', you need to manually specify the parameter names in Kotlin when calling the methods.

It's failing on my method where I just define the class. I'm not calling the method. On the "didFinishLaunchingWithOptions" line below.

import platform.UIKit.UIApplication
import platform.UIKit.UIApplicationDelegateProtocol
import platform.darwin.NSObject

class AppDelegate : NSObject(), UIApplicationDelegateProtocol {

    override fun application(
        application: UIApplication,
        didFinishLaunchingWithOptions: Map<Any?, *>?
    ): Boolean {
        return true
    }

}

I wonder if you have resolved that.
Just simply adding class AppDelegateKotlin : NSObject(), UIApplicationDelegateProtocol in the iOS main and nowhere even using it - breaks the iOS build

Okay I see that the hint to fix the issue is another topic and is about just suppressing conflicting overloads

@file:Suppress(
    "CONFLICTING_OVERLOADS",
    "PARAMETER_NAME_CHANGED_ON_OVERRIDE",
    "RETURN_TYPE_MISMATCH_ON_OVERRIDE"
)

Still wonder if I should continue implementing iOS' AppDelegate in kotlin because of other possible pitfalls

I ended up building out the AppDelegate in Swift to fulfill my requirements. I combined SKIE so that I could easily consume flows from the common module and it seems to work well.
