What problem does it solve? Building iOS apps that feel native requires deep knowledge of Apple's Human Interface Guidelines and SwiftUI APIs, and getting navigation, typography, colors, and accessibility right without guidance leads to inconsistent, non-compliant interfaces. ## Core Features & Use Cases - SwiftUI Layout & Components: Provides stack-based layouts, adaptive grids, lists, forms, buttons, sheets, and loading states following HIG spacing and typography standards. - Navigation Patterns: Covers NavigationStack, NavigationSplitView, TabView, sheets with detents, deep linking, and coordinator-based routing for iOS 16 through iOS 18. - HIG Compliance & Accessibility: Supplies semantic colors, Dynamic Type support, SF Symbols usage, VoiceOver labels, haptic feedback, and dark mode-safe styling. - Use Case: When building a new iOS settings screen, use this Skill to generate a Form with grouped sections, semantic colors, searchable navigation, and proper accessibility modifiers that pass App Store review. ## Quick Start Use the mobile-ios-design skill to build a SwiftUI settings screen with grouped form sections, navigation, and dark mode support.
