title: Xcode 6. Class Sizes, looks completely different at run time than on Interface Builder and preview

  <p>I've spent a lot of time making this work in all sizes ([Any,Any],[Compact,Any],[Regular,Regular] etc...), all looks good in 'Preview' (which I <strong>thought</strong> was supposed to simulate run time) and having it all looks completely different on Simulator/Device.</p>
  
  <p>I've removed all constraints and rebuild many times. Using "Reset To Suggested Constraints.." is a complete mess (use to work perfectly), I've add them manually.</p>
  
  <p>If a visual tool is so unpredictable, what else can I do other than go back to using two storyboards? </p>
