The user interface style adopted by the view controller and all of its children.
- iOS 13.0+Beta
- tvOS 13.0+Beta
Use this property to force the view controller to always adopt a light or dark interface style. The default value of this property is
UIUser, which causes the view controller to inherit the interface style from the system or a parent view controller. If you assign a different value, the new style applies to the view controller, its entire view hierarchy, and any embedded child view controllers.
