Play a sound file on repeat in Swift?

Question

I have had success playing sounds by pressing a button, by using the following code. However, I'd like to press a button and have that sound play in a loop/infinitely. How is this acheived? I'd also like to acheive pause/play functionality as well. Thanks in advance.

@IBAction func keyPressed(_ sender: UIB`utton) {

            playSound(soundName: sender.currentTitle!)

    }


    func playSound(soundName: String) { //
        let url = Bundle.main.url(forResource: soundName, withExtension: "wav")
        player = try! AVAudioPlayer(contentsOf: url!)
        player.play()

    } // End of Play Sound

Answer 1

By default AVAudioPlayer plays its audio from start to finish then stops, but we can control how many times to make it loop by setting its numberOfLoops property. For example, to make your audio play three times in total, you’d write this:

 player.numberOfLoops = 3

if you want the infinite loop then use

 player.numberOfLoops =  -1  

for e.g

  func playSound(soundName: String) { //
        let url = Bundle.main.url(forResource: soundName, withExtension: "wav")
        player = try! AVAudioPlayer(contentsOf: url!)
        player.numberOfLoops =  -1 // set your count here 
        player.play()

    } // End of Play Sound

var audioPlayer: AVAudioPlayer?

    func startBackgroundMusic() {
        if let bundle = Bundle.main.path(forResource: "Guru_Nanak_Sahib_Ji", ofType: "mp3") {
            let backgroundMusic = NSURL(fileURLWithPath: bundle)
            do {
                audioPlayer = try AVAudioPlayer(contentsOf:backgroundMusic as URL)
                guard let audioPlayer = audioPlayer else { return }
                audioPlayer.numberOfLoops = -1 // for infinite times
                audioPlayer.prepareToPlay()
                audioPlayer.play()
            } catch {
                print(error)
            }
        }
    }
