title: Simulator and Storyboard Preview Difference
body: <p>Currently, I'm using Xcode 6 Beta 6 for this thread. I have this single view application for iOS 8.0 and iPhone devices only. That single view have the value <code>Inferred</code> under the <code>Attribute Inspector</code> > <code>Simulated Metrics</code>.</p>
  
  <p>At first I didn't try to apply the <code>Add Missing Constraints</code> since I'm trying to layout the view to support a single layout both for 3.5" and 4" display. After running the current view - WYSIWYG on the simulator. That's fine and correct. When I tried to apply <code>Add Missing Constraints</code>, the changes applied to the base storyboard as well as to the device previews. But when I tried to run the application on the simulator, it wasn't the same.</p>
  
  <p>What went wrong here?</p>
