Playback

playAudio(…)

A static method that accepts an AVAudioPlayer and a TimeInterval in order to initiate playback of an audio file.

static func playAudio(_ audio: AVAudioPlayer, delay: TimeInterval) {
    audio.prepareToPlay()
    let time = DispatchTime.now() + Double(Int64(delay * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC)
    DispatchQueue.main.asyncAfter(deadline: time) {
        audio.play()
    }
}

For example, the following will play the audio file associated with myPlayer after a delay of 1s.

Sound.playAudio(myPlayer, delay: 1.0)
