操作无法完成。 （OSStatus 错误 2003334207。）

Question

I know this is a duplicate question but I did not find any solution that works for me.

I am using AVAudioPlayer to play an audio with the url which I am getting from Firebase . The url I get from Firebase is:

https://firebasestorage.googleapis.com:443/v0/b/unified-45b5c.appspot.com/o/AudioMessage%2F5%2B8_5_Audio_07-09-20224:07:30.m4a?alt=media&token=af3aabce-46bd-4d55-a7ca-30623eaf1817

if I open this url on google chrome it gives me my audio. But when I try it using AVAudioPlayer it gives me the following error:

The operation couldn't be completed. (OSStatus error 2003334207.)

This is what I am doing:

Button {  
 
         vm.startPlaying(url: audioURL ?? URL(fileURLWithPath: "")) 
        } label: {

            Image(systemName: startAudio ? "pause.fill" : "play.fill")
                .foregroundColor(.black)
                .padding()
                .background(
                    RoundedRectangle(cornerRadius: 10)
                        .foregroundColor(.gray)
                        .frame(width: 100)
                )
        }

And the function startPlaying() :

    func startPlaying(url : URL) {
                    
           do {
               audioPlayer = try AVAudioPlayer(contentsOf : url)
               audioPlayer.prepareToPlay()
               audioPlayer.play()
                   
           } catch {
               Helper.shared.printDebug("Playing Failed")
               Helper.shared.printDebug(error.localizedDescription)  // error: The operation couldn’t be completed. (OSStatus error 2003334207.)
           }
                   
       }

Answer 1

The initializer you are using for AVAudioPlayer expect an URL to a local file. You can't pass it a URL to a file on a remote server. To quote the docs:

Declaration
init(contentsOf url: URL) throws
Parameters
url
A URL that identifies the local audio file to play

You'll need to download the data to a local file before playing it, or use a method that supports streaming audio playback.

Answer 2

Duncan's solution works if you want to download the item first, and then play it. If you want more like a streaming experience, you can useAVPlayer , which is built to allow playing remote files, and helps with streaming:

Use an instance of AVPlayer to play local and remote file-based media, such as QuickTime movies and MP3 audio files, as well as audiovisual media served using HTTP Live Streaming.

let player = AVPlayer(playerItem: item) 
let audio = AVPlayerItem(url: url)
player.play()

Note that you can keep an instance of the player to play multiple items
