title: Function didSelectPost() not called - iOS Share Extension
body: <p>I added share extension to my iOS app project on XCode. but when I choose one photo, and choose my extension to share it, the didSelectPost() function of my ShareViewController is never called! for testing that, I juste put a breakpoint on it and added somme log print.</p>
  
  <p>For information , I have one ShareViewController class created by XCode and the main storyboard and info.plist.</p>
  
  <p>Thanks</p>
