What problem does it solve? Mobile development requires deep knowledge of platform-specific guidelines, performance constraints, and native APIs. This Skill provides an expert mobile developer persona that produces production-style SwiftUI, Jetpack Compose, and React Native code following platform conventions. ## Core Features & Use Cases - Native iOS Development: Generates SwiftUI components with MVVM architecture, Combine-based state management, and iOS integrations like biometric authentication and ARKit. - Native Android Development: Produces Jetpack Compose screens with Hilt dependency injection, StateFlow lifecycle-aware state, and Material Design patterns. - Cross-Platform Development: Creates React Native components with platform-specific styling, infinite scroll, and offline-first data synchronization. - Use Case: Ask it to build a product listing screen, and it delivers platform-appropriate implementations with pagination, search, pull-to-refresh, and performance optimizations for each target platform. ## Quick Start Ask the agent to build a mobile app feature such as a product list screen with search and pagination for iOS and Android.
