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

Decision Tree: Platform Selection

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)
