title: EKEvent.notes returns (null) even when EKEvent.hasNotes returns YES
body: <p>I'm on Xcode 6.0.1, making a test app with Event Kit. The following code successfully populates each event's title, but its notes are returned as (null) even when hasNotes property returns YES. And, I can see the notes for the same event on iPhone's default calendar app.</p>
  
  <p>What am I doing wrong?</p>
