ios - 显示 SwiftUI 屏幕时自动播放音频

Question

我想显示如下所示的传入屏幕。在显示此屏幕时，我想播放铃声文件(mp3)。我在窗口对象之前添加了 Sound.playSounds(soundfile: "ringing.mp3") 行。但是mp3文件没有播放，但是playsounds函数正在执行。

    DispatchQueue.main.async{
        Sound.playSounds(soundfile: "ringing.mp3")

        let window = UIApplication.shared.windows.first
        let contentView = IncomingCallView(viewNavigator: ViewNavigator())
        window?.rootViewController = UIHostingController(rootView:contentView )
        window?.makeKeyAndVisible()
    }

声音文件如下所示

import AVFoundation

class Sound {

    static var player:AVAudioPlayer?

    static func playaudio(soundfile: String) {

        if let path = Bundle.main.path(forResource: soundfile, ofType: nil){
            print("<<<<<<<<<<<<<<<<<<<<<PATH >>>>>>>>>>>>>>>>>>>>>>>>>",path)
            do{

                player = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: path))
                player?.prepareToPlay()
                player?.play()

            }catch {
                print("<<<<<<<<<<<<<<<<<<<<<Error >>>>>>>>>>>>>>>>>>>>>>>>")
            }
        }
    }
}

使用出现方法

SomeView()
    .onAppear{ Sound.playAudio }
