title: How to remove iOS 8 extensions?
body: <p>I am having a problem. I tested the extensions in my application and I can't get rid of them now.<br>
  I tried deleting the application, cleaning the project, opening in simulator, other device but this problem persists.<br>
  I don't have targets and the files in the project but still the share options appear and i can't disable them. Is this a bug or am i missing something?</p>
