title: Switching to landscape, auto constraints in wrong corner
body: <p>I'm presenting a view controller when my view controller is rotated to horizontal.</p>
  
  <p>In my NIb, I have a help button with constraints to margin top and right of 8 pixels each. However, my view controller displays with the button in the top right of a Portait perspective. See image. How do I make this show up in top right in Landscape?</p>
