SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps React Native developers use SwiftUI-style views and modifiers in Expo without guessing how to map SwiftUI concepts into the Expo UI API.

Core Features & Use Cases

  • SwiftUI-like Components & Modifiers: Use @expo/ui/swift-ui for views and @expo/ui/swift-ui/modifiers for modifiers, mirroring SwiftUI’s mental model.
  • Correct Host Wrapping: Ensures every SwiftUI tree is wrapped in Host, avoiding structural runtime issues.
  • RN Interop via RNHostView: Embeds React Native components inside a SwiftUI tree using RNHostView for mixed UI stacks.
  • Use Correct Versioned Docs (SDK 55): Guides you to the right Expo documentation pages for v55.0.0 to prevent API mismatches.
  • Extension Path (Optional): Provides a safe approach for extending missing views/modifiers via a local Expo module, with explicit confirmation before doing so.

Quick Start

Install the package with npx expo install @expo/ui.

FAQPage Schema
How do I use SwiftUI components and modifiers in my Expo React Native app?

To use SwiftUI components and modifiers in Expo, install @expo/ui, import views from @expo/ui/swift-ui and modifiers from @expo/ui/swift-ui/modifiers, mirroring SwiftUI’s mental model within your React Native project.

Why does my Expo SwiftUI UI crash or fail to render correctly at runtime?

Expo SwiftUI UI rendering issues often occur when the SwiftUI tree is not wrapped in the Host component, which ensures correct structural wiring and prevents runtime failures.

Can I embed standard React Native components inside a SwiftUI tree in Expo?

Yes, you can embed React Native components inside a SwiftUI tree using RNHostView, allowing you to build mixed UI stacks that interoperate between native RN and SwiftUI.

How do I add a missing SwiftUI view or modifier that is not supported by Expo UI?

To add missing SwiftUI views or modifiers, safely extend the UI by creating a local Expo module, validating the new APIs against the v55 Expo SwiftUI documentation to prevent mismatches.

Does Expo UI support SwiftUI components for SDK 55?

Yes, this approach targets React Native developers building SwiftUI-like screens specifically for SDK 55, guiding you to the correct v55.0.0 Expo documentation URLs to avoid API mismatches.
