What can I do to fix Bottom layout is deprecated iOS 11, I am using Xcode 9 beta 2.
Function of @paper1111 works fine in Xcode Version 9.3.1, but for me not worked first time. After two days of World War with Interface Builder
Solution:
1) check the "Use safe area layout guides" button in the File Inspector of the Interface Builder.
2) uncheck the "Use safe area layout guides" button in the File Inspector of the Interface Builder.
3) check again the "Use safe area layout guides" button in the File Inspector of the Interface Builder.
4) (a possible additional step) clean the build folder In the menu select Product --> Clean Build Folder. Or hold Shift+Command+K
