Play audio file in a sequence in swift - ios

Question

I have two functions. First one loops list of names for audio to be played, and the second one is the actual player function. The problem is that it plays only the last one. It does not play one by one waiting till the next is finished. How it possible to perform in a sequence? I tried to add: dispatch_after(DISPATCH_TIME_NOW, dispatch_get_main_queue(), { }) ... still does not work. Any possible solution. Thank you in advance!
func startGame(){
audioPlay("NowListen")
for i in 0...self.soundArray.count - 1 {
print(self.soundArray[i])
self.audioPlay(self.soundArray[i])
}
}
func audioPlay(name: String){
var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("\(name)", ofType: "mp3")!)
print(alertSound)
// try to play sound
do{
self.audioPlayer = try AVAudioPlayer(contentsOfURL: alertSound)
self.audioPlayer.prepareToPlay()
self.audioPlayer.play()
} catch {
}
}

Answer 1

Use AVQueuePlayer ( init it with Items at the start and it will play in queue, one after another ) class instead of AVAudioPlayer.
In your Start Game, you can do following:
var audioItems: [AVPlayerItem] = []
for audioName in soundsArray {
let url = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(audioName, ofType: "mp3")!)
let item = AVPlayerItem(URL: url)
audioItems.append(item)
}
let player = AVQueuePlayer(items: audioItems)
player.play()
