title: SWIFT - MPMediaPickerController -init error
body: <p>I have two view controllers, one with mediapicker and one with the actual player.
  so i done this code:</p>
  
  <p>first view</p>
  
  <pre><code>import UIKit
  import MediaPlayer
  
  class WelcomeView: UIViewController, MPMediaPickerControllerDelegate {
  
  override func viewDidLoad() {
  super.viewDidLoad()
  var mediaPicker: MPMediaPickerController = MPMediaPickerController.self(mediaTypes:MPMediaType.Music)
  mediaPicker.allowsPickingMultipleItems = false
  mediapicker1 = mediaPicker
  mediaPicker.delegate = self
  }
  
  override func didReceiveMemoryWarning() {
  super.didReceiveMemoryWarning() }
  
  var mediapicker1 = MPMediaPickerController()
  
  @IBAction func selectsong(sender: AnyObject) {
  self.presentViewController(mediapicker1, animated: true, completion: nil)
  }
  
  func mediaPicker(mediaPicker: MPMediaPickerController!, didPickMediaItems mediaItemCollection: MPMediaItemCollection!) {
      self.dismissViewControllerAnimated(true, completion: nil)
      println("you picked: \(mediaItemCollection)")
      selectedelement = mediaItemCollection
  
      let vc = MainView(nibName: "MainView", bundle: nil)
      navigationController?.pushViewController(vc, animated: true) 
  }
  
  var selectedelement = MPMediaItemCollection()
  override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
      var DestView: MainView = segue.destinationViewController as MainView
      DestView.selectedsong = selectedelement
   }}
  </code></pre>
  
  <p>and the player view </p>
  
  <pre><code>import UIKit
  import MediaPlayer
  
  class MainView: UIViewController {
  
  var play = MPMusicPlayerController()
  var selectedsong = MPMediaItemCollection()
  
  override func viewDidLoad() {
  super.viewDidLoad()
  
      func prepareToPlay() -&gt; Bool{
      let myplayer = MPMusicPlayerController.applicationMusicPlayer()
      myplayer.setQueueWithItemCollection(selectedsong)
      play = myplayer
      myplayer.play()
      return true
      }}
  
  override func didReceiveMemoryWarning() {
  super.didReceiveMemoryWarning()
  }}
  </code></pre>
  
  <p>but when i tap start the xcode gives me this error:
  "MPMediaItemCollectionInitException', reason: '-init is not supported, use -initWithItems:"</p>
  
  <p>I searched on google about this, and found something like "I not actually running the query in the background"</p>
  
  <p>so i dont realy understand what to do))</p>
