title: Can't drag outlets from Storyboard to Assistant editor in XCode
body: <p>I used to be able to do this in XCode, and now suddenly I can't in a new project I've opened that was sent over by a friend.</p>
  
  <p>Is there a particular setting I have to change to start this again?</p>
  
  <p>I.e. there is a textbox I want to link via Code, and now I just can't. :(</p>
  
  <p>Need help guys!</p>
