# Expo UI (`@expo/ui`) `@expo/ui` renders real native UI from React: SwiftUI on iOS, Jetpack Compose on Android. Start with its universal components (one tree for iOS, Android, and web) and drop to platform-specific SwiftUI/Jetpack Compose only when the universal layer falls short. It also ships drop-in replacements for migrating off RN community UI libraries. > These instructions track the latest Expo SDK. The **universal** layer requires **SDK 56+**. Drop-in replacements and the platform-specific layers also exist on SDK 55. For component details on a specific SDK, refer to the Expo UI docs for that version. ## Installation ```bash npx expo install @expo/ui ``` On SDK 56, `@expo/ui` works in Expo Go, so `npx expo start` runs it directly — no custom build required. On older SDKs, build a dev client first (`npx expo run:ios` / `npx expo run:android`). Every `@expo/ui` tree — universal or platform-specific — must be wrapped in `Host`. ## Choosing an approach (read this first) Work down this list and stop at the first layer that meets the need: 1. **Universal components — start here.** Import from the `@expo/ui` root. One component tree runs unmodified on iOS, Android, and web from a single source (Compose on Android, SwiftUI on iOS, `react-native-web`/`react-dom` on web). No platform file splits. → `./references/universal.md` 2. **Platform-specific (SwiftUI / Jetpack Compose).** Import from `@expo/ui/swift-ui` or `@expo/ui/jetpack-compose`. Use **only** when the univ...
