Mobile Patterns

1. Cross-Platform Architecture

• Shared Core: Maximize business logic sharing between platforms using cross-platform frameworks (React Native, Flutter) or KMM (Kotlin Multiplatform Mobile).
• Platform-Specific UI: Respect platform conventions (iOS Cupertino vs Android Material) when appropriate, using platform-specific file extensions or conditional rendering.

2. Navigation Patterns

• Stack Navigation: Push new screens onto the stack and pop them off to go back.
• Tab Navigation: Provide quick access to top-level views.
• Drawer Navigation: Use a hidden side menu for secondary navigation.
• Deep Linking: Configure URLs that navigate directly to specific content within the app.

3. Native Module Integration

• Bridging: Write custom native code (Java/Kotlin or Objective-C/Swift) and expose it to JavaScript/Dart.
• Turbo Modules / JSI: (React Native) Use direct C++ integration for high-performance synchronous calls.
• Platform Channels: (Flutter) Communicate between Dart and native code securely.

4. Offline-First

• Local Database: Use SQLite, WatermelonDB, or Realm to persist data locally.
• Sync Strategies: Implement optimistic UI updates and background sync queues.
• Conflict Resolution: Handle data conflicts between local edits and remote server state.

5. Push Notifications

• FCM / APNs: Configure Firebase Cloud Messaging for Android and Apple Push Notification service for iOS.
• Rich Notifications: Include images, action buttons, and custom payloads in notifications.
• Badge Management: Keep the app icon badge count in sync with unread notifications.

6. Performance

• FPS Monitoring: Aim for 60fps (or 120fps) for smooth animations and interactions.
• Memory Management: Profile memory usage to avoid OOM (Out Of Memory) crashes, especially with image-heavy views.
• Startup Time: Optimize app load time by deferring non-critical initializations.

7. App Store & Deployment

• Metadata: Prepare compelling descriptions, keywords, and release notes.
• Screenshots: Generate localized, high-resolution screenshots for all required device sizes.
• Versioning: Follow semantic versioning and increment build numbers automatically.

8. CI/CD

• Fastlane: Automate beta deployments, releases, and screenshots.
• EAS (Expo Application Services): Manage builds and OTA (Over The Air) updates for React Native.
• Code Signing: Manage provisioning profiles and keystores securely.
• TestFlight / Play Console: Distribute beta builds to testers and manage the release tracks.
