Expo UI SDK 55: Jetpack Compose Moves to Beta for React Native Developers
Key Takeaways
- ▸Jetpack Compose graduated from alpha to beta with a complete set of Material Design 3 components, validated through a production WikiReader app
- ▸SwiftUI APIs were reworked to match Apple's conventions, enabling developers to transfer native framework knowledge directly to Expo UI
- ▸Expo UI's strategy exposes native frameworks directly rather than reimplementing them, ensuring developers always access the latest platform features
Summary
Expo has advanced Jetpack Compose support from alpha to beta in SDK 55, enabling React Native developers to access Google's native Android UI framework directly within their apps. The update includes a comprehensive set of Material Design 3 components—such as Card, LazyColumn, ListItem, DockedSearchBar, and ModalBottomSheet—validated through a production app (WikiReader) built entirely with Expo UI. Alongside Jetpack Compose's beta release, SwiftUI APIs have been refined to align more closely with Apple's conventions, reducing the learning curve for developers familiar with either native framework.
Expo UI's core philosophy is to expose native frameworks directly rather than reimplementing them in JavaScript, ensuring developers gain access to new platform features as they ship. This approach allows developers and AI systems with knowledge of SwiftUI or Jetpack Compose to write Expo UI code without learning proprietary abstractions. By bridging React Native with native component libraries, Expo aims to eliminate the maintenance burden of keeping JavaScript implementations synchronized with rapid updates from Apple and Google.
- The approach benefits both human developers and AI systems, as it uses conventional native APIs rather than proprietary abstractions
Editorial Opinion
Expo UI represents a pragmatic shift in cross-platform development philosophy: instead of fighting to keep JavaScript abstractions in sync with rapidly evolving native frameworks, expose the native frameworks themselves. This beta milestone for Jetpack Compose validates that the approach works at production scale, and the alignment with native API conventions makes it genuinely accessible to developers who already know SwiftUI or Compose. For teams building cross-platform apps, this could significantly reduce maintenance burden while improving access to platform features.
