expo-ui
Build native UI with the @expo/ui package: real SwiftUI on iOS and Jetpack Compose on Android rendered from React in an Expo or React Native app. Covers universal cross-platform components (Host, Column, Row, Button, Text, List, and more imported from @expo/ui), drop-in replacements for popular React Native community libraries (BottomSheet, DateTimePicker, Slider, Menu, etc.), and platform-specific SwiftUI (@expo/ui/swift-ui, iOS only) and Jetpack Compose (@expo/ui/jetpack-compose, Android only) trees and modifiers. Use when adding or reviewing @expo/ui Host/RNHostView trees, building native-feeling UI where standard React Native components fall short (grouped settings forms with toggles, sections, menus, sheets, pickers, sliders), choosing between universal and platform-specific components, or replacing an RN community UI library with a native @expo/ui equivalent. Not for custom native modules, Expo Router navigation, Reanimated, or data fetching.

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
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:
-
Universal components — start here. Import from the
@expo/uiroot. One component tree runs unmodified on iOS, Android, and web from a single source (Compose on Android, SwiftUI on iOS,react-native-web/react-domon web). No platform file splits. →./references/universal.md -
Platform-specific (SwiftUI / Jetpack Compose). Import from
@expo/ui/swift-uior@expo/ui/jetpack-compose. Use only when the universal layer is missing a component or modifier you need, or when you need platform-specific behavior or optimization. Downside: you write two trees and split them into.ios.tsx/.android.tsxfiles (or branch onPlatform.OS) — more code to maintain.@expo/ui/swift-uiis iOS-only.@expo/ui/jetpack-composeis Android-only. Importing either in a file that runs on the other platform will crash at runtime with "Unable to get view config" errors. Isolate platform-specific trees in.ios.tsx/.android.tsxfiles placed incomponents/(never insideapp/— Expo Router does not support platform extensions for route files), or guard withPlatform.OSin a regular route file.Hostmust always be imported from@expo/ui(the universal package root), not from the platform-specific sub-packages. →./references/swift-ui.mdand./references/jetpack-compose.md
Already using an RN community UI library? @expo/ui also ships drop-in replacements — API-compatible swaps for popular libraries (@gorhom/bottom-sheet, @react-native-community/datetimepicker, and more), imported from @expo/ui/community/<name>. This is a migration side-path for replacing an existing dependency, not a step in the universal-vs-platform decision above. → ./references/drop-in-replacements.md
