Automatic Preferred Max Layout Width is not available on iOS versions prior to 8.0

Question

I opened an existing iOS project with Xcode6 beta6, and Xcode lists the following warning for both Storyboard and Xib files:

Automatic Preferred Max L

Answer 1

I got it working by selecting the original layout I had in the W / H selection. Storyboard is working as expected and the error is gone.

Be also sure that you are developing for iOS 8.0. Check that from the project's general settings.

This is where you should press.
