将 AVAudioPlayer 与 swiftUI 一起使用时在滑块上移动拇指的问题

如何解决将 AVAudioPlayer 与 swiftUI 一起使用时在滑块上移动拇指的问题

使用 swiftUI（最新版本为 2 月 24 日）

我正在播放音频文件 (soundFile.mp3)，一切正常。 （移至结尾、开头、+/- 15 秒、暂停、播放）

但是，我无法通过滑块上的“拇指”手动移动滑块。 但是当我暂停音频时，拇指会随着音频播放和停止而移动

有人对我如何解决这个问题有任何想法吗？？？？

将不胜感激

swiftUI 文件（删减一点）如下：

...

import SwiftUI
import AVFoundation

var audioPlayer: AVAudioPlayer?

struct ContentView: View {
        
    @State private var sound: String = "soundFile"
    @State private var type: String = "mp3"
    
    @State private var myTime:CGFloat = 0
    @State private var timeDuration:CGFloat = 10
    @State private var myDuration:CGFloat = 10
    @State var currentValue = 4.0
    @State var myCurrentTime = 4.0
    @State var isPlaying: Bool = true





    var body: some View
    {
