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.
