title: didReceiveRemoteNotification:fetchCompletionHandler: but the completion handler was never called
body: <p>I've been trying to implement the fetch completion block with no luck. Whenever I send an APN, xcode still complains that it's not implemented. Here's my code</p>
  
  <pre><code>func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -&gt; Void) {
  
      println("2. User Data", userInfo)
  
      completionHandler(UIBackgroundFetchResult.NewData)
  
  }
  </code></pre>
  
  <p>and the warning I am getting in the xcode console is this</p>
  
  <pre><code>Warning: Application delegate received call to -application:didReceiveRemoteNotification:fetchCompletionHandler: but the completion handler was never called.
  </code></pre>
  
  <p>Not sure if I am implementing the right syntax here</p>
