SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Developing mobile apps requires deep knowledge of platform-specific guidelines, performance constraints, and native APIs across iOS, Android, and cross-platform frameworks, which is difficult to manage consistently. ## Core Features & Use Cases - Native Development: Implements iOS apps with SwiftUI and Android apps with Jetpack Compose following Material Design and Human Interface Guidelines. - Cross-Platform Support: Builds React Native and Flutter applications with platform-specific optimizations and code-sharing strategies. - Platform Integrations: Handles biometric authentication, push notifications, camera, geolocation, and in-app purchases. - Use Case: You need a product listing app for both iOS and Android. The Skill generates SwiftUI and Jetpack Compose components with MVVM architecture, pagination, search, and offline-first data synchronization. ## Quick Start Ask the agent to design and implement a mobile app feature, specifying your target platforms and framework preference such as SwiftUI, Jetpack Compose, or React Native.

Frequently Asked Questions about Mobile App Builder

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a cross-platform mobile app with React Native?▼

React Native lets you share code across iOS and Android while applying platform-specific styles via Platform.select. The Skill generates components with FlatList optimization, safe area handling, and infinite query pagination using @tanstack/react-query.

Should I choose native development or cross-platform for my mobile app?▼

Choose native (SwiftUI for iOS, Jetpack Compose for Android) when you need deep platform integration and maximum performance. Choose React Native or Flutter when code sharing and faster multi-platform delivery matter more than platform-specific polish.

How do I implement offline-first architecture in a mobile app?▼

Offline-first architecture uses local storage with intelligent data synchronization so the app works without network connectivity. On iOS this typically uses Core Data, on Android Room with WorkManager, combined with caching and refresh strategies.

Does SwiftUI support MVVM architecture with async data loading?▼

Yes, SwiftUI supports MVVM using ObservableObject view models with @Published properties and async/await for data loading. The Skill demonstrates this pattern with @MainActor view models, task modifiers, and searchable list interfaces.

What performance targets should a mobile app meet?▼

The Skill targets app startup under 3 seconds, memory usage under 100MB for core functionality, battery drain under 5% per hour of active use, and a crash-free rate above 99.5% across supported devices.
