UIKit — Apple framework reference

UIKit is the primary framework for building event-driven graphical user interfaces on iOS, providing the views, controls, and app lifecycle infrastructure your app is constructed from. Use it to lay out interfaces with constraints expressed through types like UILayoutPriority, and to compose and render rich text using the TextKit object graph, including NSTextContentStorage, NSTextLayoutManager, NSTextContainer, and NSTextLayoutFragment. Style and measure that text with NSParagraphStyle and NSMutableParagraphStyle, NSTextAlignment, NSLineBreakMode, NSUnderlineStyle, and NSShadow, and embed inline content through NSTextAttachment and NSTextList. The framework also supports data-driven UI and resource handling with types such as NSDiffableDataSourceSectionSnapshotReference and NSDataAsset, and runs on iOS, tvOS, watchOS, and visionOS.
