Swift: AudioPlayerDidFinished will not be called - swift

Question

My AudioPlayerDidFinishPlaying will not be called after audio has finished. I know it has something to do with my delegate, but I can't fix it on my own.
Can somebody give me some tips? I Googled a lot and I found other questions here with the same issue but it didn't work for me.
Thanks

Answer 1

you're not setting yourself as the player's delegate
before calling play() do player.delegate = self

Answer 2

if you are using private delegate then its will not call too use this for resolving this issue
//MARK:- This is correct delegate working fine (use this)
func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool) {
audioRecorder = nil
}
//MARK:- Insted of this (this will not call)
private func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool) {
audioRecorder = nil
}
