title: Can't drop a view onto another. Am zoomed in. xcode 6.3.2
body: <p>This should be simple. I have a view controller on the storyboard. I am zoomed in. I try to drag and drop another view controller on top of it and it won't work. I've never had this problem before. I have restarted xcode with no help.</p>
  
  <p>What's my problem?</p>
  
  <p>Thanks.</p>
