Ios 在Swift 5中播放我的项目中的随机声音

我是iOS新手。我编写了这段代码，当点击UIButton时，它只播放一个音频文件。我想随机播放多个声音。如何设置？谢谢大家!

import UIKit
import AVFoundation


class ViewController: UIViewController {

    var audioPlayer: AVAudioPlayer!

    @IBAction func playButtonPressed(_ sender: UIButton) {
           if let soundURL = Bundle.main.url(forResource: "kompilacja", withExtension: "mp3") {

                do {
                    audioPlayer = try AVAudioPlayer(contentsOf: soundURL)
                }
                catch {
                    print(error)
                }

                audioPlayer.play()
            }else{
                print("Karwasz twarz! Brak pliku audio, Panie!")
            }
        }


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }


}

将所有声音文件名放在一个数组中，并使用randomElement方法选择声音

@IBAction func playButtonPressed(_ sender: UIButton) {
    let sounds = ["kompilacja", "another sound", "yet another sound"]
    guard let sound = sounds.randomElement(),
        let soundURL = Bundle.main.url(forResource: sound, withExtension: "mp3") else { return }

    do {
        audioPlayer = try AVAudioPlayer(contentsOf: soundURL)
    }
    catch {
        print(error)
    }

    audioPlayer.play()
}
