Did anyone manage to define AppDelegate class directly in iosMain kotlin source set? I tried a couple of different things and couldn’t make it work. My latest code is in the thread 🧵.

My custom AppDelegate class
`InspektifyAppDelegate.kt`:

class InspektifyAppDelegate: NSObject(), UIApplicationDelegateProtocol {
}

Usage of it in swift code
`iOSApp.swift`:

import SwiftUI
import ComposeApp

@main
struct iOSApp: App {
    @UIApplicationDelegateAdaptor(InspektifyAppDelegate.self) var appDelegate

    init() {
        KoinImplKt.doInitKoin()
	}

    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

Error that I am getting when trying to run iOS app:

error: generic struct 'UIApplicationDelegateAdaptor' requires that 'InspektifyAppDelegate' conform to 'UIApplicationDelegate'
    @UIApplicationDelegateAdaptor(InspektifyAppDelegate.self) var appDelegate
     ^

SwiftUI.UIApplicationDelegateAdaptor:4:43: note: where 'DelegateType' = 'InspektifyAppDelegate'
@MainActor @propertyWrapper public struct UIApplicationDelegateAdaptor<DelegateType> : DynamicProperty where DelegateType : NSObject, DelegateType : UIApplicationDelegate {

*__attribute__*((unavailable("Kotlin subclass of Objective-C class can't be imported")))
*__attribute__*((swift_name("InspektifyAppDelegate")))
*@interface* SharedInspektifyAppDelegate : NSObject
@end

this is not working

I found this answer on stackoverflow:

Will try to replicate it for that custom view and then used it with AppDelegate.

Good luck 🚀
