Swift - AVAudioPlayer not playing sound

I have a sound called speeding.mp3 and I am trying to make a AVAudioPayer instance with it by doing this in the root of the class:

let speedingAudioPlayer = try! AVAudioPlayer(contentsOfURL: NSBundle.mainBundle().URLForResource("speeding", withExtension: "mp3")!)

Then when I run the app it throws an error but I don't know why this is happening. The speeding.mp3 file is in the Bundle Resources drop down in Build Phases so it should find it fine. If I try to print out the URL in the simulator and paste it into Safari it loads and plays the file like normal. I am importing AVFoundation into the class and the framework into the project.

import UIKit
import AVFoundation

class CustomAudioPlayer {
  var audioPlayer : AVAudioPlayer!

  override func viewDidLoad() {
    super.viewDidLoad()
    playSound("sound_file_name")
  }

  func playSound(soundName: String)
  {
    let alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(soundName, ofType: "mp3")!)
    do{
        audioPlayer = try AVAudioPlayer(contentsOfURL:alertSound)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
    }catch {
        print("Error getting the audio file")
    }
  }
}

Try this code for playing the sound.

I found another question where the var is placed outside the class because otherwise it would be deallocated by the phone.

Use this code snippet to debug your error, 

if let URL = NSBundle.mainBundle().URLForResource("speeding", withExtension: "mp3") {
    do {
        let speedingAudioPlayer = try AVAudioPlayer(contentsOfURL: URL)
    } catch  let error as NSError {
        print(error.localizedDescription)
    }
} else {
    print("No such file exist")
}
