start playing audio from a background task via AVAudioPlayer in Xcode

Question

I am trying to start playing a sound from a background task via an AVAudioPlayer that is instantiated then, so here\'s what I\'ve got.

For readability I cut out all user

Answer 1

What fixed it for me was to start playing some audio just as application quits, so I added 1sec blank audio in applicationWillResignActive in the AppDelegate

func applicationWillResignActive(_ application: UIApplication) {

        self.backgroundUpdateTask = UIApplication.shared.beginBackgroundTask(expirationHandler: {
            self.endBackgroundUpdateTask(true)
        })


        let secSilence = URL(fileURLWithPath: Bundle.main.path(forResource: "1secSilence", ofType: "mp3")!)

        do {
            audioPlayer = try AVAudioPlayer(contentsOf: secSilence)
        }
        catch {
            print("Error in loading sound file")
        }

        audioPlayer.prepareToPlay()
        audioPlayer.play()



}
