If you initialise your AVAudioPlayer like var wrongMusicPlayer: AVAudioPlayer = AVAudioPlayer() OR wrongMusicPlayer = AVAudioPlayer() in any method then please remove it and just Declare like var wrongMusicPlayer: AVAudioPlayer!.

Thanks, Rakesh! It's amazing! My game broke on iPhone with iOS 13.1.2. But in simulator it's work. On physical device - no! I read a lot of forums, online books, docs, etc.

And this small fix really helped me: I changed var player = AVAudioPlayer() to var player: AVAudioPlayer!

p.s. guys wrote about problem with threads but this case is simpler

Answer 3

The same issue happens with Objective C code.

Previously musicPlayer = [[AVAudioPlayer alloc] init]; would work but will now cause a crash in iOS13. The crash happens later on when using one of the other init methods like initWithContentsOfURL.

Removing the [[AVAudioPlayer alloc] init] fixes the issue.

Answer 4

iOS 13.2, which be released today, fixes this issue.
