如何通过AVAudioPlayer当前时间更新播放器滑块处理当前值

guard let url = Bundle.main.url(forResource: "audio", withExtension: "mp3") else { return }
do {
    audioPlayer = try AVAudioPlayer(contentsOf: url)
    audioPlayer.delegate = self
} catch {
    print("Failed to load audio file")
}

@IBOutlet weak var slider: UISlider!

slider.addTarget(self, action: #selector(sliderValueChanged(_:)), for: .valueChanged)

@objc func sliderValueChanged(_ sender: UISlider) {
    let currentTime = Double(sender.value) * audioPlayer.duration
    audioPlayer.currentTime = currentTime
}

func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool) {
    slider.value = 0.0
}
