OSStatus error 2003334207 when using AVAudioPlayer

Question

I am trying to play an MP3 file (works when played via VLC/iTunes) when a button is pressed. Here is my code:

     var audioPlayer: AVAudioPlayer!
     @IBAc

It looks like your trying to unwrap a variable that has a nil value. You should safely unwrap your variables to prevent this.

if let data: CDEpisode = fetchedResultsController.objectAtIndexPath(indexPath!) as! CDEpisode
{
    var err: NSError?
    let url = NSURL(string: data.localPath)
    println("The url is \(url)")

    //rest of code
}

You will still need to figure out why it is returning nil but this is a safer way to unwrap variables and prevent crashing as there would need to be more context to resolve that issue.

Some questions to look into:

• Are you sure the fetchedResultsController is returning an object at all?
• Are you sure it is of CDEpisode?
