I have two audio players in my application:
1. AVQueuePlayer - used for playing sound effects.
2. AVPlayer - used for playing heavier audio content that can run in the background.
Issue:
The sound effect player (AVQueuePlayer) triggers the playback completion listener of the AVPlayer, which causes the usingBlock callback to execute unintentionally. I believe this happens because I am using NSNotificationCenter.defaultCenter. (Note: The sound effect player does not have or require a listener.)
Here's my code:

kotlin


private val notificationCenter = NSNotificationCenter.defaultCenter

/**
 * Sets up a listener for playback completion.
 */
private fun setupPlaybackCompletionListener() {
    // This listener is currently listening to all AVPlayers
    listener = notificationCenter.addObserverForName(
        name = AVPlayerItemDidPlayToEndTimeNotification,
        `object` = null,
        queue = null,
        usingBlock = { notification ->
            if (notification.toString().contains("audio"))
                handlePlaybackCompletion()
        }
    )
}

Attempted Solution:
If I try to replace NSNotificationCenter.defaultCenter with a new instance (NSNotificationCenter()), the usingBlock is not triggered at all, which is problematic.
Current Workaround:
I'm currently inspecting the NSNotification? provided in usingBlock to check if the AVPlayerItem URL contains "audio", which indicates it's a normal audio rather than a sound effect. However, I feel this is not an ideal solution.
Question:
Is there a better way to prevent the sound effect player from triggering the listener for the AVPlayer, while still ensuring the AVPlayer listener works as intended?

I don’t think it’s a kotlin issue, go look at iOS slack/forum, it will be easier for you to find help.
