Working on getting Expo SDK ready for the new iPhone Duo has been super interesting. Thanks to @huntie and @__ubax__ for all the insanely great work! #expo
Today is the day to fold your apps π
We wrote a guide you can give to your agents to get started.
On iPhone Duo your status bar and tab bar move into a rail on the side, so ππππππ.πππ is 0 now. This guide from @huntie, @__ubax__, and @chrfalch will help you adjust your apps for the fold:

While trying to deprecate Cocoapods and add support for SwiftPM in Expo and React Native almost at the same time can make me a bit dizzy, stuff like this really makes me happy: github.com/Shopify/react-natβ¦ - SwiftPM in RNSkia π€© @wcandillon
So many insanely cool things coming.
π π Expo SDK 58 beta is out. Built for iOS 27 on React Native 0.88 RC, with ππ‘ππ-πππ-πππππππ for Siri, @ππ‘ππ/πππππ-πππ for coding agents, and Expo Modules 2.0 in beta....and tons more.

Tons of delicious details in the changelog: expo.dev/changelog/sdk-58-beβ¦
Looking good... πΏ#expo
Excited to see RN #SwiftPM PRs being merged in community libraries - lottie-react-native, op-sqlite, posthog-js and powersync-js have all merged PRs using the new SwiftPM pipeline in React Native 0.87! Thanks for the feedback - already fixed some issues you found in 0.87.1!
Taking a week off now feels like missing at least 4 MS Builds, 3 WWDCs, and a few App.js conferences at the same timeβthings are happening at such speed these days. Looking forward to be able to use Fable and ChatGPT 5.6 when I'm back. π΄π
This has been (and still is) a lot of fun. Making stuff faster! #expo
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 details β
It feels to me like Fable is a lot better than Opus - it just doesn't struggle with anything - builds it directly without any issues... Working on testing out some Expo Universal components in #Expo SDK-56 and it just fixes everything.π₯
Wow... Back from #Appjs 2026 - this was a really fantastic experience! Thanks for having me on stage - looking forward to show more of the Swift PM support in React Native!
Long nights and great solutions creates awesome SDKs. So proud of being part of this - thanks to the awesome Expo SDK Team π₯
Expo SDK 56 is out π
β Expo UI is stable on iOS and Android
β iOS builds 16% faster, plus another 20% on EAS from precompiled community libs
β Android cold starts 40% faster
β Expo Router decoupled from React Navigation
β Inline native modules: write Swift and Kotlin right next to your TypeScript
β Hermes v1 by default
β Bytecode diffing on by default (~58% smaller OTA updates)
β iOS Widgets stable
β React Native 0.85 + React 19.2
It's been two months since SDK 55, and we packed in everything we could fit. Your iOS build times are going to thank you. Full changelog β
Speed, Widgets, Expo UI, Inline Native Modules, Expo Router and Brownfield. Huge beta release.
We just cut the SDK 56 beta π
β 50%+ faster iOS builds (precompiled XCFrameworks) β 40% faster cold starts on Android
β Expo UI is stable
β iOS widgets are stable
β expo-router rebuilt from scratch
β Inline native modules
β Brownfield multi-app support
The obvious themes are speed and stability. But there are a lot of other interesting changes (like Expo Router decoupling itself form React Navigation). Get all the nuance and detail in the changelog below β
Looking forward to start talking more about the SPM transition in React Native. Itβs going to be big. #appjsconf
So proud to be part of this awesome team π₯
π Expo is the best it's ever been, and it's about to get a lot better.
We raised a Series B so we can go faster on the things that matter to you: faster builds, smoother native integrations, and the services to make end-to-end app development a delightful experience.
There is a lot of work to do. This round led by @Georgian_io puts us in position to go do it!
So happy to see React Native animations being disrupted like this - it will result in huge steps forward for RN devs.
npm i react-native-ease
Reanimated is an incredible library.
But react-native-ease by @appandflow is opening the door to new possibilities.
Pure native animations. No JS thread.
Built this particle cube with EaseView, then recreated it with Reanimated.
What do you think?
Seeing agents fail like this when asked to create an avatar from my profile picture makes me believe Iβll have a job next year as well.
This is both impressive and interesting. Great work, @janicduplessis! π₯
