Agora无法使用iOS Swift录制通话

我在这里遵循文档：并实现一个基本的记录。这是我的代码：

    func startRecording(){
        let filename = getDocumentsDirectory().appendingPathComponent("\(APP_NAME)\(now()).WAV")
        let str = String(describing: filename)
        self.recordingPath = str
        agoraKit?.startAudioRecording(str, quality: .high)
    }


    func stopRecording(){
     
        agoraKit?.stopAudioRecording()
        
        // get audio file
        guard let audioUrl = URL(string: self.recordingPath) as? URL else { return }
        
        DispatchQueue.main.asyncAfter(deadline: .now() + 2.0 ) { [weak self] in

            // getdata
            do {
                let myData = try Data(contentsOf: audioUrl)
                print(myData.count, myData)
            } catch {
                print(error)
            }

        }        

    }
    
private func getDocumentsDirectory() -> URL {
    let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
    return paths[0]
}

但是我得到了错误：

文件“Whisper1608949569.WAV”无法打开，因为没有这样的文件

完整信息：

file:///var/mobile/Containers/Data/Application/1F682ABD-153C-4DFD-BFF4-

02C1CE6F9A4C/Documents/Whisper1608949569.WAV
Error Domain=NSCocoaErrorDomain Code=260 "The file “Whisper1608949569.WAV” couldn’t be opened because there is no such file."

我是否无法正确访问该文件

以下是我初始化agora客户端的方式：

    self.agoraKit = AgoraRtcEngineKit.sharedEngine(withAppId: AppID, delegate: self)
    agoraKit?.delegate = self
    agoraKit?.enableWebSdkInteroperability(true)

    // sample loudest speaker every second
    agoraKit?.enableAudioVolumeIndication(1000, smooth: 3, report_vad: true)

    agoraKit?.enableAudio()
    
    // config for livecast to start
    agoraKit?.setChannelProfile(.liveBroadcasting)
    
    // set framrate and HD/SD
    agoraKit?.setVideoEncoderConfiguration( CONFIG_PRODUCTION )
    
    //agoraKit?.setDefaultAudioRouteToSpeakerphone(true)

我刚刚查看了您正在使用的文档中引用的文档，文档中说该方法现在已被弃用，您应该将此方法与附加的sampleRate参数一起使用：

同时检查startAudioRecording和stopAudioRecording的返回值是否返回0，表示成功。

文档是针对目标C。。但是我在找SWIFT，你看到了吗？在autocomplete中有额外的sampleRate参数的.startAudioRecording方法？它应该是这样的：

agoraKit？.startAudioRecording（str，sampleRate:32000，质量：。高）
