I have background music playing on a loop during a blackjack app but when a phone call is recieved the music does not restart. The loop is in the form of a SKAudioNode which seems to work well in conjuction with other audio that occurs as the game is played. I found using audioPlayer for background music caused it to stop when the sound file for placing chips etc is played. The rest of the game works fine after disconnecting the phone call. Exiting the app and then restarting still doesnt restart the background music. Is there a function for handling this type of interruption so the music starts where it left off ?

    var backgroundMusic: SKAudioNode!

    override func didMove(to view: SKView) {
    if let musicURL = Bundle.main.url(forResource: "playlistbj", withExtension: "mp3") {
    backgroundMusic = SKAudioNode(url: musicURL)
        addChild(backgroundMusic)}

}
