AVAudioPlayer.initWithData throwing exception

Question

I am trying to play the audio from remote URL.

let audioData = try! Data.init(contentsOf: URL)
do       
 {
      self.audioPlayer = try AVAudioPlayer.init(data: data) //Throwing error sometimes
      self.audioPlayer?.delegate = self
      self.audioPlayer?.prepareToPlay()     
      self.audioPlayer?.play()

 }
 catch {
          showErrorMessage("An error occurred while trying to extract audio file")

  }

I have a list of audio url on my server. for some audio I am able to get the Data but in the AVAudioPlayer's init method it is throwing the error. I am not able to get the actual cause for this.

I have the option of AVPlayer but why this thing is causing the issue?

I try it by the code below and its work fine

  let audioData = try! Data.init(contentsOf: url)
    do
    {
        let audioPlayer = try AVAudioPlayer.init(data: audioData) //Throwing error sometimes
        audioPlayer.delegate = self as? AVAudioPlayerDelegate
        audioPlayer.prepareToPlay()
        audioPlayer.play()

    } catch {
        print("An error occurred while trying to extract audio file")
    }

Yes , It works fine with most of the urls but we are using some audio jungle urls which are causing the issue. – Bindiya Apr 24 '18 at 07:24
Or If you want to try with this specific url which is causing Issue - https://s3.envato.com/files/142154780/preview.mp3 – Bindiya Apr 24 '18 at 07:49

Just directly Play Audio From URL you have as

do
{
  try Manager.player = AVAudioPlayer.init(contentsOf: returnPathAtSelectedIndex(fileName: fileName))
  //Set required delegates and Values

  Manager.player?.delegate = self
  Manager.player?.volume = 1.0
  Manager.player?.prepareToPlay()
  Manager.player?.play()
}
catch
{
  print("Error while playing music: \(error.localizedDescription)")
}

My Player

struct Manager 
{
   ///AVAudio Player
    static var player: AVAudioPlayer?
}

My function func returnPathAtSelectedIndex(fileName:String) -> URL Returns a URL.

Edit

As the AVAudioPlayer plays the file saved into the local. You need to save the file to local and than

AVAudioPlayer.init(contentsOf:localFileUrl)

will help to play the file and won't generate the crash.

I have to use that audio file later so downloading the audio to `Data` is compulsory. – Bindiya Apr 24 '18 at 07:33
You can Manage the download procedure as a Separate Thread, Like BackGround downloading, URL can be used to play file as one thread, and use Data of URL as Separate Thread , So load wont be on one Controller only , Hope you getting my point – iOS Geek Apr 24 '18 at 09:30
Yes I tried with local audio file URL and It worked with me. – Bindiya Apr 24 '18 at 10:30

Please change your code to this, so you can know more what kind of error is happening:

let audioData = try! Data.init(contentsOf: URL)
do {
   self.audioPlayer = try AVAudioPlayer.init(data: data) //Throwing error sometimes
   self.audioPlayer?.delegate = self
   self.audioPlayer?.prepareToPlay()     
   self.audioPlayer?.play()

}
catch let error {
   print(error.localizedDescription)
   showErrorMessage(error.localizedDescription)

}

Yes, Just did that and got to know the issue. – Bindiya Apr 24 '18 at 07:27 — Bindiya, Apr 24 '18 at 07:27

After debugging the localised description I was getting the error

The operation couldn’t be completed. (OSStatus error 1954115647.)

and below link helped me to resolve my issue.

Instead of initializing the audio player with the NSData object, save the file to the Documents folder, and then initialized the player with the file URL
