iOS simulator only shows app in a quarter of the screen

Question

Since 2 days, when starting the app in the emulator it opens the app 1/4 of the screen size. iPhone 6 and tested it with the iPhone 6 Plus as well... even home is quarter-sized

'Cleaned' the project, 'Reset contents and settings' of the iOS simulator. But still not solved.

Quiting and relaunching the simulator did not work. As you can see in the bottom screenshot changing the scale does not help.

The problem does not apear in version 'Xcode 7 Beta 4'.

Answer 1

I am quite new in iOS. I had the same problem, this is what I did and resolved

1 - xcode 7.1.1.
2 - In the file Inspector, right hand Pane
3 - In "Interface Builder Document", I chose Xcode 5.1; the one I used to do programming before El Capitan and new Xcode installed.
