The Apple UIKit framework offers the necessary infrastructure for building iOS and tvOS applications. The framework provides the display and windows architecture for applying user interface; the main Runloop required to handle interactions between your apps, the system, and the users; and the infrastructure that handle the event for delivering Multi-Touch and any other forms of input to your application.
Aside from that, the Apple UIKit framework offers other features such as accessibility support, animation support, app extension support, document support, drawing and printing support, information about the current device, resource management, search support, and text management and display. The Apple UIKit is used by app developers and web developers.Ansett Apple UIKit Developers
