title: Swift Int is not convertible to DictionaryIndex?
body: <p>I'm trying to convert this piece of ojb-c code:</p>
  
  <pre><code>MPMovieFinishReason finishReason = [notification.userInfo[MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] integerValue];
  </code></pre>
  
  <p>to swift, and as such I have this:</p>
  
  <pre><code>var finishReason: MPMovieFinishReason = notification.userInfo[MPMoviePlayerPlaybackDidFinishReasonUserInfoKey.integerValue];
  </code></pre>
  
  <p>However this gives me the error in the title.
  What am I doing wrong here?</p>
