Overview
Starting in iOS 8, you should employ the UITrait and UITrait APIs, and size class properties as used in those APIs, instead of using UIInterface constants or otherwise writing your app in terms of interface orientation.
In earlier versions of iOS, you used these constants in the status property and the set method. Notice that UIDeviceis assigned to UIInterface and UIDevice is assigned to UIInterface; the reason for this is that rotating the device requires rotating the content in the opposite direction.
