Mobile Development Skill — Quick Reference

This skill equips mobile developers with execution-ready patterns for building native and cross-platform mobile applications. Apply these patterns when you need iOS/Android app architecture, UI components, navigation flows, API integration, offline storage, authentication, or mobile-specific features.

When to Use This Skill

Use this skill when you need:

  • 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 (APNs, FCM)
  • Camera and media access
  • Location services
  • App Store / Play Store deployment
  • Mobile performance optimization
  • Offline-first architecture
  • Deep linking and universal links

Core Capabilities

iOS Development

  • UI Frameworks: SwiftUI (declarative), UIKit (imperative)
  • Architecture: MVVM, Clean Architecture, Coordinator, TCA (Composable Architecture)
  • Concurrency: Swift Concurrency (async/await, actors, TaskGroup); keep UI state on @MainActor; enable strict concurrency checks as appropriate
  • Storage: Core Data, SwiftData, Keychain
  • Networking: URLSession, async/await patterns
  • Platform compliance: Privacy manifests + required-reason APIs, background execution limits, and accessibility settings (Dynamic Type, VoiceOver)
  • Defensive Decoding: Handle missing fields, array/dict formats, snake_case/camelCase

Android Development

  • UI Frameworks: Jetpack Compose (declarative), Views (XML)
  • Architecture: MVVM, Clean Architecture, MVI
  • Concurrency: Coroutines, Flow, LiveData
  • Storage: Room, DataStore, Keystore
  • Networking: Retrofit, OkHttp, Ktor

Cross-Platform Development

  • Kotlin Multiplatform (KMP): Share domain/data/networking; keep native UI; consider Compose Multiplatform when shared UI is worth the constraints
  • React Native: JavaScript/TypeScript; evaluate New Architecture readiness and native-module surface area; Expo-managed path is often fastest for greenfield apps
  • Flutter: Dart; high code sharing; validate platform-specific gaps and plugin maturity for your requirements
  • WebView: WKWebView (iOS), WebView (Android), JavaScript bridge

Platform Baselines (Verify Current Requirements)

iOS/iPadOS (Core)

Android (Core)

Cross-Platform (Core)

  • Feature parity is explicit (document what is native-only vs shared) [Inference]
  • Bridges are treated as public APIs (versioned, tested, and observable) [Inference]
  • React Native upgrades follow the official upgrade guide; validate New Architecture readiness against your native-module surface area https://reactnative.dev/docs/upgrading
  • Expo SDK upgrades follow Expo release notes and upgrade guides https://expo.dev/changelog

Optional: AI/Automation Extensions

Note: Skip unless the app ships AI/automation features.

Common Patterns

App Startup Checklist

  1. Initialize dependencies

    • Configure DI container (Hilt/Koin/Swinject)
    • Set up logging and crash reporting
    • Initialize analytics

  2. Check authentication state

    • Validate stored tokens
    • Refresh if needed
    • Route to login or main screen

  3. Configure app state

    • Load user preferences
    • Set up push notification handlers
    • Initialize deep link handling

Offline-First Architecture

1. Local-first data access
   - Always read from local database
   - Display cached data immediately
   - Show loading indicator for sync

2. Background sync
   - Queue write operations
   - Sync when connectivity available
   - Handle conflict resolution

3. Optimistic updates
   - Update UI immediately
   - Sync in background
   - Rollback on failure

Push Notification Setup

iOS (APNs):
1. Enable Push Notifications capability
2. Request user permission
3. Register for remote notifications
4. Handle device token
5. Implement notification delegate

Android (FCM):
1. Add Firebase to project
2. Implement FirebaseMessagingService
3. Handle notification/data messages
4. Manage notification channels (Android 8+)
5. Handle background/foreground states

Performance Optimization

Area iOS Android Metric
Launch time Pre-warm, lazy loading Cold start optimization < 2s cold start
List scrolling LazyVStack, prefetch LazyColumn, paging 60 FPS
Image loading AsyncImage, cache Coil/Glide, disk cache < 100ms visible
Memory Instruments profiling LeakCanary, Profiler No memory leaks
Battery Background App Refresh limits Doze mode compliance Minimal drain

App Store Deployment Checklist

iOS App Store

  • App icons (all required sizes)
  • Launch screen configured
  • Privacy manifest per target and embedded frameworks (iOS 18+)
  • Required-reason APIs declared with justifications
  • Third-party SDK privacy manifests attached; SDK signature attestation (iOS 19+)
  • Info.plist permissions explanations
  • App Store screenshots (all device sizes)
  • App Store description and keywords
  • Privacy policy URL
  • TestFlight beta testing

Google Play Store

  • App icons and feature graphic
  • Store listing screenshots
  • Privacy policy URL
  • Content rating questionnaire
  • Target API level compliance
  • Data safety form
  • Internal/closed/open testing tracks

Navigation

Resources

Shared Checklists

Shared Utilities (Centralized patterns — extract, don’t duplicate)

Templates

Anti-Patterns to Avoid

Anti-Pattern Problem Solution
Blocking main thread UI freezes, ANRs Use async/coroutines for all I/O
Massive view controllers Hard to test/maintain Extract to MVVM/services
Hardcoded strings No localization Use NSLocalizedString/strings.xml
Ignoring lifecycle Memory leaks, crashes Respect activity/view lifecycle
No offline handling Poor UX without network Cache data, queue operations
Storing secrets in code Security vulnerability Use Keychain/Keystore
Using decode() without fallback Crashes on missing/malformed API data Use decodeIfPresent() with defaults
Missing @Bindable for @Observable NavigationStack bindings don’t work Add @Bindable var vm = vm in body

Trend Awareness Protocol

IMPORTANT: When users ask recommendation questions about mobile development, you MUST use a web search capability (if available) to check current trends before answering. If web search is unavailable, say so and answer using data/sources.json, clearly flagging that the recommendation may be stale.

Trigger Conditions

  • “What’s the best mobile framework for [use case]?”
  • “What should I use for [cross-platform/native/hybrid]?”
  • “What’s the latest in iOS/Android development?”
  • “Current best practices for [Swift/Kotlin/React Native]?”
  • “Is [React Native/Flutter/Expo] still relevant in 2026?”
  • “[React Native] vs [Flutter] vs [native]?”
  • “Best approach for [offline/push/deep linking]?”

Required Searches

  1. Search: "mobile development best practices 2026"
  2. Search: "[iOS/Android/React Native/Flutter] updates 2026"
  3. Search: "mobile framework comparison 2026"
  4. Search: "[Expo/Swift/Kotlin] new features 2026"

What to Report

After searching, provide:

  • Current landscape: What frameworks/approaches are popular NOW
  • Emerging trends: New patterns or tools gaining traction
  • Deprecated/declining: Approaches that are losing relevance
  • Recommendation: Based on fresh data and recent releases

Example Topics (verify with fresh search)

  • Current iOS + Swift Concurrency migration guidance
  • Current Play target SDK policy and identity/auth guidance
  • React Native New Architecture maturity and upgrade pain points
  • Expo-managed vs bare React Native tradeoffs
  • Flutter vs React Native vs KMP ecosystem in 2026
  • Compose Multiplatform readiness for iOS in 2026
