One import gives you SwiftUI on iOS and Jetpack Compose on Android. No JS reimplementation. Check out Expo UI:

React Native hasn't shipped a new UI primitive in years. No slider. No date picker. No segmented control. So you install a community package and pray it survives your next upgrade. @expo UI kills that. Real native SwiftUI + Jetpack Compose components, written in JSX. 30-min

Just rebuilt Apple’s iMessage text effects in React Native 🔥 Invisible Ink, Slam, Shimmer, Bounce, Glitch, and more. 60fps, buttery smooth with React Native Skia. All running natively on iOS & Android. This was only possible thanks to @wcandillon & @chrfalch ❤️ #ReactNative

Upgrading your Expo app has never been smoother. These days you can hand the whole upgrade to Claude Code or Codex with the expo/skills library. We see a lot of people having success with this. Obviously every app is a bit different so we also have a full guide to help you

🙌 Thank you @ReactSummit Amsterdam! You made us feel like stars. This was our first time sponsoring the event and we loved it. We'll see you again next year 🫡. We're taking all this big, nerdy momentum and riding it into Chain React Conf next month. Limited time only 50%

The fastest mobile build is the one you never run. Most CI/CD reruns a full iOS build even when you only touched JavaScript. EAS Workflows knows when not to build. So we compared the top mobile CI/CD tools for 2026. Expo's biased, but we kept it honest. ↓

Here's Expo''s biggest CICD differentiator: Fingerprint + repack: ◆ It checks if your native layer actually changed ◆ If it didn't, skip the full build ◆ Repack the last binary with the new JS on top With this workflow a ~15 min build becomes ~2 min.

Your iOS builds just got faster. No changes required. SDK 56 ships Expo modules as precompiled XCFrameworks: instead of compiling them from source on every build, your app links binaries that were already built. On by default, locally and on EAS Build. @chrfalch shares all the

Chain React Conf is important. This is the only North American conference where React and React Native devs can gather in person to trade ideas (and feelings) about how software development is changing. The talks we have curated for the event are going to alter careers.
