Mobile Development Skill — Quick Reference
This skill equips mobile developers with execution-ready patterns for building native and cross-platform mobile applications. Claude should apply these patterns when users ask for iOS/Android app architecture, UI components, navigation flows, API integration, offline storage, authentication, or mobile-specific features.
When to Use This Skill
Claude should invoke this skill when a user requests:
- iOS app development (Swift, SwiftUI, UIKit)
- Android app development (Kotlin, Jetpack Compose)
- Cross-platform development (React Native, WebView)
- Mobile app architecture and patterns
- Navigation and routing
- State management (Redux, MobX, MVVM)
- Network requests and API integration
- Local data storage (Core Data, Room, SQLite)
- Authentication and session management
- Push notifications
- Camera and media access
- Location services
- App Store / Play Store deployment
- Mobile performance optimization
- Offline-first architecture

Need to build mobile app for: [Target Audience]
├─ iOS only?
│ └─ Use Swift + SwiftUI (templates/swift/)
│
├─ Android only?
│ └─ Use Kotlin + Jetpack Compose (templates/kotlin/)
│
├─ Both iOS and Android?
│ ├─ Need maximum performance?
│ │ └─ Build separate native apps (Swift + Kotlin)
│ │
│ ├─ Need faster development + code sharing?
│ │ └─ Use React Native (templates/cross-platform/)
│ │
│ └─ Wrapping existing web app?
│ └─ Use WebView wrapper (templates/cross-platform/template-webview.md)
