Auto Layout is a powerful technology that allows you to create a single user interface which automatically adjusts to screen size, orientation, and localization. With Xcode 5, Interface Builder’s support for Auto Layout has been greatly enhanced. Interface Builder offers as much or as little help as you like, giving you a free-form canvas on which to create your next great app. Xcode offers helpful alerts when constraints are missing or mis-configured, and Interface Builder can even fix the layout for you.
