SKILL.md

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

Quick Reference Table

Task iOS Android Cross-Platform When to Use
Native UI SwiftUI + UIKit Jetpack Compose + Views React Native Native: Best performance; Cross-platform: Code sharing
Navigation NavigationStack Navigation Component React Navigation Platform-specific for native feel
State Management @State/@Observable ViewModel + StateFlow Redux/MobX iOS: @Observable; Android: ViewModel; RN: Redux
Networking URLSession + async/await Retrofit + Coroutines Axios/Fetch Native: Type-safe; RN: JavaScript ecosystem
Local Storage Core Data + SwiftData Room Database AsyncStorage/SQLite Native: Full control; RN: Simpler
Push Notifications APNs FCM React Native Firebase Native: Platform-specific; RN: Unified API

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)
