title: Swift 3 - device tokens are now being parsed as '32BYTES'
body: <p>I just updated from Xcode 7 to the 8 GM and amidst the Swift 3 compatibility issues I noticed that my device tokens have stopped working. They now only read '32BYTES'.</p>
  
  <pre><code>    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
  {
      print(deviceToken) // Prints '32BYTES'
      print(String(data: deviceToken , encoding: .utf8)) // Prints nil
  }
  </code></pre>
  
  <p>Before the update I was able to simply send the NSData to my server, but now I'm having a hard time actually parsing the token.</p>
  
  <p>What am I missing here?</p>
  
  <p>Edit: I just testing converting back to NSData and I'm seeing the expected results. So now I'm just confused about the new Data type.</p>
  
  <pre><code>    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
  {
      print(deviceToken) // Prints '32BYTES'
      print(String(data: deviceToken , encoding: .utf8)) // Prints nil
  
      let d = NSData(data: deviceToken)
      print(d) // Prints my device token
  }
  </code></pre>
