AppKit

iOSmacOStvOSwatchOSvisionOS

AppKit is the core macOS application UI framework, providing the windows, views, controls, alerts, and event handling you use to build Mac apps. You assemble interfaces from cells and controls such as NSActionCell, present modal warnings through types coordinated by NSAlertDelegate, and support assistive technologies with a broad accessibility layer including NSAccessibilityElement, NSAccessibilityCustomRotor, and protocols like NSAccessibilityButton, NSAccessibilitySlider, and NSAccessibilityTable. The framework also covers text layout through NSATSTypesetter and pointer-precision interactions via NSAlignmentFeedbackFilter.
