I am trying to locate a URL which is only pure .m4a sound with my application. I have the URL to the audio and theoretically download it. Then, with the downloaded fileURL to th

Answer 1

I had the same problem and I choosed an alternative solution as app doc said:

A file URL for the temporary file. Because the file is temporary, you must either open the file for reading or move it to a permanent location in your app’s sandbox container directory before returning from this delegate method.

The idea is just to copy from tmp directory to document directory and play from document directory.

Create a member variable:

var player = AVAudioPlayer()

Now implement your downloadSound method as below:

func downloadSound(url:URL){
    let docUrl:URL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL!
    let desURL = docUrl.appendingPathComponent("tmpsong.m4a")
    var downloadTask:URLSessionDownloadTask
    downloadTask = URLSession.shared.downloadTask(with: url, completionHandler: { [weak self](URLData, response, error) -> Void in
        do{
            let isFileFound:Bool? = FileManager.default.fileExists(atPath: desURL.path)
            if isFileFound == true{
                  print(desURL) //delete tmpsong.m4a & copy

                try FileManager.default.removeItem(atPath: desURL.path)
                try FileManager.default.copyItem(at: URLData!, to: desURL)

            } else {
                try FileManager.default.copyItem(at: URLData!, to: desURL)
            }
            let sPlayer = try AVAudioPlayer(contentsOf: desURL!)
            self?.player = sPlayer
            self?.player.prepareToPlay()
            self?.player.play()

        }catch let err {
            print(err.localizedDescription)
        }
            
        })
    downloadTask.resume()
}

This is just a sample solution.
