I'm trying to implement PTChannelManagerDelegateProtocol in iosMain and I'm getting "Conflicting overloads" exceptions. The confusing part to me is that the methods all have unique parameter names. Here is an example of two methods:

public open fun channelManager(channelManager: PTChannelManager, didActivateAudioSession: AVAudioSession): 
public open fun channelManager(channelManager: PTChannelManager, didDeactivateAudioSession: AVAudioSession):

How do I resolve these errors?

You can use the name of the parameter to distinguish

It's not compiling though. That is the issue.

class PushToTalkManager(
): NSObject(), PTChannelManagerDelegateProtocol, PTChannelRestorationDelegateProtocol {
}

This is how I'm trying to use it.

[Landry Norris]

I see. You're overriding, not calling. I remember running into this before and fixing it, but don't remember off hand how I resolved this.

[Landry Norris]

The worst-case solution I can think of is to use a cinterop def file to create an abstract class in Obj-C that implements this, and provides methods with different names, then extend that in Kotlin, but that's obviously not a good experience.

[Landry Norris]

Can you just suppress the error? I think some of these K/N oddities are suppressable.

[Trey]

Android Studio isn't suggesting any way to suppress. I'll dig through the docs some more.

Parameter names are not important in the signature of a method. The signature consist only of the function name and the ordered parameter types. So in your case, both functions have the same name and the same ordered parameter types. So having different parameter names does not help

[Landry Norris]

@Suppress("CONFLICTING_OVERLOADS")

[Trey]

That suppresses the error. 🙂

[Landry Norris]

The methods come from an Obj-C interface, where unfortunately, the name of a parameter is part of the method's signature.

[Trey]

I'll clean this up and hopefully it will build. Thanks for the help!

[Deepak Nulu]

@Landry Norris ah, ok.

[Landry Norris]

I could have sworn there was an annotation that told the compiler about this condition, but I may just be thinking of the suppress.
