How to fix AVAudioPlayer issue in my code? - ios

Question

Thanks for visiting this question.
I recently started learning swift. I'm making an audio player ish app.
The nextButton works only for a couple of times, and then it just becomes silent. I'm trying to make an array loop over and over if nextButton is being pressed. So, it means when I press the "next" button, it will go to the next track and if tracks from array finished, it will play all track over again.
All I'm trying to achieve it to get the "next" button work without any stops.
Array and Audio Player:
let sound1 = NSURL(fileURLWithPath: Bundle.main.path(forResource: "1", ofType: "mp3")!)
let sound2 = NSURL(fileURLWithPath: Bundle.main.path(forResource: "2", ofType: "mp3")!)
let sound3 = NSURL(fileURLWithPath: Bundle.main.path(forResource: "3", ofType: "mp3")!)
lazy var soundArray: [NSURL] = [sound1, sound2, sound3]
var audioPlayer = AVAudioPlayer()
var run = true
var currentIndex = 0
func playRandomSound() {
let randNo = Int(arc4random_uniform(UInt32(soundArray.count)))
if run == true{
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)
try AVAudioSession.sharedInstance().setActive(true)
try audioPlayer = AVAudioPlayer(contentsOf: soundArray[randNo] as URL)
audioPlayer.prepareToPlay()
audioPlayer.play()
} catch {
print(error)
}
}
}
nextButton:
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
currentIndex = indexPath.row
}
#IBAction func nextButton(_ sender: Any) {
audioPlayer.stop()
print("Audio did stop")
if currentIndex + 1 < soundArray.count {
currentIndex += 1
playRandomSound()
}
}
Full Code:

animation.subtype = CATransitionSubtype.fromTop
animation.duration = 1
self.layer.add(animation, forKey: CATransitionType.push.rawValue)
self.text = text
}
}
