Мне нужно вызвать следующую песню после окончания первой песни в AVAudioPlayer

Я хочу, чтобы следующая песня воспроизводилась после окончания первой. Как я могу решить это? Я проверил документацию Apple. Но я не нашел ничего полезного для меня. 

import UIKit
import AVFoundation

class ViewController: UIViewController {
    var arrayOfSounds = ["sting", "hotel"]
    var audioPlayer : AVAudioPlayer?
    var isPlaying = false
    var timer:Timer!

    func setupAudioPlayer(file: NSString, type: NSString){
        let path = Bundle.main.path(forResource: file as String, ofType: type as String)
        let url = NSURL.fileURL(withPath: path!)
        do {
            try  audioPlayer =  AVAudioPlayer(contentsOf: url)
        } catch {
            print("Player not available")
        }
    }


    override func viewDidLoad() {
        super.viewDidLoad()

    }

    @IBOutlet weak var Slider: UISlider!

    @IBAction func changeSlider(_ sender: UISlider) {
        audioPlayer?.stop()
        audioPlayer?.currentTime = TimeInterval(Slider.value)
        audioPlayer?.prepareToPlay()
        audioPlayer?.play()
       }



    @IBAction func playSound(_ sender: UIButton) {

        let range: UInt32 = UInt32(arrayOfSounds.count)
        let number = Int(arc4random_uniform(range))

        self.setupAudioPlayer(file: arrayOfSounds[number] as NSString, type: "mp3")
       if isPlaying == true {
        audioPlayer?.pause()
                isPlaying = false
            } else {
        audioPlayer?.play()
                isPlaying = true
            }
    }


    @IBAction func nextSound(_ sender: UIButton) {
        let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: "sting", ofType: "mp3")!)

        do{
            audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)

        }catch {
            print("there was some error. The error was \(error)")
        }
        audioPlayer?.play()
    }

    @IBAction func lastSound(_ sender: UIButton) {
        let soundURL = NSURL(fileURLWithPath: Bundle.main.path(forResource: "hotel", ofType: "mp3")!)

            do{
                audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
            }catch {
                print("there was some error. The error was \(error)")
            }
        audioPlayer?.play()
        }

    func audioPlayerDidFinishPlaying(audioPlayer: AVAudioPlayer, successfully: Bool) {
        print("Good")
        }

    }
