ios-design-system

iOS design system engineering for SwiftUI — token architecture, color system engineering, typography scales, spacing tokens, component style libraries, asset management, theming, and governance. This skill should be used when building, organizing, or maintaining a design system for an iOS app, refactoring ad-hoc styles into tokens, creating reusable component styles (ButtonStyle, LabelStyle), structuring asset catalogs, or preventing style drift and duplication.
