title: Loop the sound alert from a Local Notification [Swift 3.0 - Xcode 8]
body: <p>Ive got Local Notifications working. However Im having trouble trying to loop the notification sound. Ive been looking through other questions on the topic, however I cannot seem to get a code to work without error.
  Im trying to loop the sound for the maximum 30 seconds allowed. The sound file is 1 sec long, so I want to loop it 29-30 times. 
  Please help!</p>
  
  <p>Heres the code:</p>
  
  <p>from the notification:</p>
  
  <pre><code>Content.sound = UNNotificationSound(named: "Note.m4a")
  </code></pre>
  
  <p>How do I loop this 30 times?</p>
