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

For some reason, even if changing the iOS Deployment Target to 8.0 or higher, the Xib files don't adopt that change and remain with the previous settings in the File inspector

Therefore, you should change it manually for each Xib

Once done, the warning will disappear :-)
