Skill UI

This skill enables integrating Expo and React Native into existing native iOS or Android applications. It covers brownfield scenarios, including embedding React Native via AAR/XCFramework or adding Expo to Kotlin/Swift projects. It supports both isolated and integrated approaches for native team collaboration.

Build Android-native UI in Expo SDK 55 with @expo/ui/jetpack-compose. Covers Compose views and modifiers, Host sizing, LazyColumn lists, Material Symbols icons, and platform-specific integration steps.

Develop native iOS applications using Swift and SwiftUI, mastering iOS 18 features, UIKit integration, Core Data, networking, and App Store optimization. Expertise includes architecture patterns, security, performance tuning, and Apple ecosystem integration for production-ready apps.

Expo DOM components allow running web code directly in native webviews, enabling the use of web-only libraries like Recharts without modification. This facilitates incremental migration of web code to native apps and supports complex HTML/CSS layouts not available in standard React Native.

A browser runtime skill that provides isolated WPE WebKit sessions, native input, screenshots, and ordered JSONL automation. Supports docker-based container lifecycle, deterministic testing, and GitHub Actions verification. Useful for reproducible browser checks and self-hosted runtime integration.
