# 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 |

## Decision Tree: Platform Selection

```text
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)
```
