title: Youtube iOS Player Helper library didn't work
body: <p>I tried to implement the youtube-ios-player-helper library to play videos in my app. I can get the player ready and load the video. And the starting thumbnail can be shown. However, when I tried to play the video, I got this error message instead:</p>
  
  <pre><code>SendDelegateMessage(NSInvocation *): delegate (webView:identifierForInitialRequest:fromDataSource:) failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode
  </code></pre>
  
  <p>And then I tried building and running the youtube ios player helper example project, and it has got the same issue. Can anybody help me with this? Thanks in advance.</p>
