title: Xcode 6, scroll view renders different in iOS7
body: <p>I am making an app in Swift, with Xcode 6 beta 7, with base SDK iOS8. I want to build a form inside a scrollview with autolayout, and I am following <a href="http://codehappily.wordpress.com/2013/11/14/ios-how-to-use-uiscrollview-with-autolayout-pure-autolayout-approach-multiple-smaller-views/" rel="nofollow noreferrer">this How-to</a>.</p>
  
  <p>It renders as expected in iOS 8 (simulator, both iPhone 4 and 5), but in iOS7.1 (Simulator or device) the scroll view seems to shift left, leaving no margin on the left and a bigger margin on the right, and the scroll indicator doesn't appear.</p>
  
  <p>iOS8:</p>

  <p>Is there anything I can do to fix this? Or should I wait Apple to fix this backward compatibility issue?</p>
