SwiftUICore

iOSmacOStvOSwatchOSvisionOS

SwiftUICore provides the core declarative UI primitives that underlie SwiftUI: views, the environment, layout, and accessibility descriptors. You use it to drive layout and animation through protocols such as Animatable, AlignmentID, and DynamicProperty, and types like AnimationContext, CubicKeyframe, and CoordinateSpace, while reading display traits through enums like ColorScheme, ColorSchemeContrast, DynamicTypeSize, and ControlSize. It also supplies accessibility descriptors and traits, including AccessibilityTraits, AccessibilityTextContentType, and AXChartDescriptorRepresentable, across iOS, macOS, tvOS, watchOS, and visionOS.
