Swift version: 5.0
AVAudioPlayer plays its audio from start to finish then stops, but you can control how many times to make it loop by setting its
numberOfLoops property. For example, to make your audio play five times in total, you’d write this:
audioPlayer.numberOfLoops = 5
You can also set this property to -1, which automatically causes
AVAudioPlayer to loop the sound forever.
Available from iOS 2.2
