I'm a bit lost on the memory management in KMM obj-c. I have AvAudioPlayer which uses a delegate AVAudioPlayerDelegateProtocol. Now I wanted to just use an anonymous implementation of that protocol (or a class extending it - they both work the same) and set it more or less like this

player.delegate = object : NSObject(), AVAudioPlayerDelegateProtocol
//or
player.delegate = MyOwnAudioPlayerDelegateImpl()

The problem is that the delegate is nullified at random times.

It works if I make the class containing the player extend AvAudioPlayerDelegateProtocol and then do player.delegate = this. But it's a bit ugly and creates different issues.

Does anyone know how I can manage memory reliably in the first scenario?

Okay, got it. Some ios classes keep their delegates as weak references. This applies to AvPlayer. The trick is to keep a strong reference to it somewhere else. Simply making it a member in the enclosing class makes it work fine.
