| description | SwiftUI implementation and Apple-platform craft — view identity/state resets, layout containers, lazy stacks/scroll performance, springs/transitions/shaders, Swift 6 concurrency, gestures/hit targets, widgets, SF Symbols, app sounds. Read the body, then one named reference. Triggers: SwiftUI, @State resets, LazyVStack, scroll stutter, spring animation, Metal shader, Sendable, actor, WidgetKit, haptics. |
SwiftUI & Apple-Platform Craft
Sources/gaps: references/sources.md maps the local WWDC/source coverage; references/coverage-gaps.md keeps API-freshness and missing-reference risks out of the router body.
Read exactly one reference file below; each carries the full distillation for its area (deeper code/source files live in a same-named subdirectory next to it).
SwiftUI core: references/swiftui-identity.md (the identity/lifetime/dependencies mental model — debug @State resets, view lifetime, structural identity here) · references/swiftui-layout.md (containers, custom Layout protocol, navigation structure) · references/swiftui-lazy-stacks.md (LazyVStack/HStack, scroll performance, stutter with large lists) · references/swiftui-animation.md (springs, transitions, keyframes, Metal shaders).
Language layer: references/swift-concurrency.md (structured concurrency, sendability, actors, Swift 6 migration, measure-first performance).
Platform craft: references/touch-interaction-design.md (gestures, hit targets, press feel on Apple platforms — web press-feel → design-craft) · references/widget-design.md (WidgetKit design: glanceable content, families, interactivity) · references/sf-symbols.md (choosing, customizing, animating SF Symbols) · references/sound-design.md (app sound: when to play sounds, designing them, haptic pairing).
Boundary splits to respect: animation on the web → web-design (web-animation-design) (the default when platform is unstated) · Apple design guidance (navigation, typography, a11y, Liquid Glass, HIG specs) stays with apple-design and apple-design (hig) — this skill owns implementation and platform craft, not design doctrine.
