title: Xcode 6 beta 7: storyboard adds extra space on right and left sides
body: <p>When I add subview to root ViewController's view, and with auto layout setup leadingSpace,trailingSpace,topSpace and bottomSpace to zero, there are appear some extra spaces on left and right sides (so if I print subview's frame its origin will be 16 and size less on 32 than should be).
  So actually we get that leading and trailing spaces are not zeros...</p>

  <p>As you can see on picture leading space - zero, but origin.x = 16</p>
  
  <p>Earlier I wasn't working hard with auto layout, so my question is: 
  Is it a bug of new Xcode or a feature?</p>
  
  <p>P.S. All frames and constraints updated.</p>
