Answer 1

You need to create an object that implements the AVAudioPlayerDelegate protocol, and use that as the delegate of the AVAudioPlayer object. Then link them together, for example:

audioPlayer = try! AVAudioPlayer(contentsOf: audioFileUrl)
audioPlayer.delegate = self

The delegate can implement methods that responds to certain events. This one fires when the audio finishes playing:

func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool) {
    // ...
}
