When a Kotlin object displays as None, its attributes and other information are not visible, but it actually holds values.

commonMain

interface ICallback {
    fun onCall(params: Map<String, Any?>)
}

object SDKManager {

    private var callback: ICallback? = null

    fun setCallback(callback: ICallback?) {
        this.callback = callback
    }
}

iosApp

import SwiftUI
import shared

@main
struct iOSApp: App {

    init() {
        class SwiftCallback : ICallback {
            func onCall(params: [String : Any]) {
            }
        }

        SDKManager.shared.setCallback(callback: SwiftCallback())
    }

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

Debug
callback ObjHeader * None 0x00000001014e0020

The correct value should be 0x1014e0020 ?

Hi, could you also share the code of SwiftCallback class?

@TadeasKriz thanks, All the codes are listed above

        class SwiftCallback : ICallback {
            func onCall(params: [String : Any]) {
            }
        }

When I debug the iOS app directly in Android Studio, the callback symbols can be displayed normally.

Thanks for the report, seems like Objective-C types don't render correctly. I'll take a look next week.

@TadeasKriz @kpgalligan Hello, may I ask if there's any progress on this issue
