title: Xcode 6: can't connect any IBOutlet to ViewController
body: <p>After upgrading to Xcode 6, I opened an old project (that contains a subproject, so it has many targets)
  and I noticed that no link from my Storyboard ViewContoller to the relative Objects works.</p>
  
  <p>For example I have a ViewController with a TableView inside and now I cant do can't do anyhing with it because the connection is missing, I can't even redefine a new IBOutlet in the VC because the arrow in the storyboard from the VC won't connect to anything.</p>
  
  <p>To be more clear: </p>

  <p>The class is defined in the Custom Class section, so I can't find the problem</p>

  <p>What should I do?
  Btw I'm using obj-c not swift, I found some related answer but all about swift.</p>
