What problem does it solve? Designing new iOS UI from scratch often produces code that compiles but misses platform conventions: hard-coded colors, fixed font sizes, missing states, no Reduce Motion handling, and accessibility gaps discovered too late. This Skill designs screens, flows, and components against Apple HIG conventions and audits the result before delivery. ## Core Features & Use Cases - Two-stage agent dispatch: An architect agent maps the task flow and produces production SwiftUI with Liquid Glass, spring animations, semantic colors, SF Symbols, and haptics; an accessibility-engineer agent then audits the fresh code for VoiceOver, Dynamic Type, touch targets, Reduce Motion, and contrast. - Project-aware design: Gathers deployment target, navigation model, color/type conventions, and component patterns from the existing project before designing, so output matches the codebase. - Verification gate: Checks output for phantom APIs, hard-coded colors, fixed font sizes, missing states (loading/empty/error), and incomplete flow maps before presenting. - Use Case: Ask it to design a settings screen for an existing SwiftUI app; it reads your deployment target and navigation style, produces compilable SwiftUI with previews and an animation inventory, then returns a severity-tagged accessibility report. ## Quick Start Ask the assistant to design a settings screen with a profile row and plan picker for your iOS app.
