Apple's reference documentation describes AppKit as follows:
AppKit contains all the objects you need to implement the user interface for a macOS app—windows, panels, buttons, menus, scrollers, and text fields—and it handles all the details for you as it efficiently draws on the screen, communicates with hardware devices and screen buffers, clears areas of the screen before drawing, and clips views.
