Hey so here is another method.
My Problem: 1.My Storyboard was showing a fat rectangle that didnt look anything like a iPhone. Then when I'd run the simulator all the element were cut off and not in the right position.2.Simulator took up the whole screen.
Resolution: 1. Make sure you Storyboard is open and displayed, click on the frame so that it has a blue highlighted border. Then on the Utilities manager (on the right) click on "Show the Attributes menu". The very first item should be Simulated Metrics. Choose the size that best fits your screen/needs.
2.Follow Adjusting the XCode iPhone simulator scale and size I scaled it down to 33%
Best,Nate
