◆ Expo UI is stable on iOS and Android
◆ iOS builds 16% faster, plus another 20% on EAS from precompiled community libs
◆ Android cold starts 40% faster
◆ Expo Router decoupled from React Navigation
◆ Inline native modules: write Swift and Kotlin right next to your TypeScript
◆ Hermes v1 by default
◆ Bytecode diffing on by default (~58% smaller OTA updates)
◆ iOS Widgets stable
◆ 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 ↓
I'm Boris and I created Claude Code. I wanted to quickly share a few tips for using Claude Code, sourced directly from the Claude Code team. The way the team uses Claude is different than how I use it. Remember: there is no one right way to use Claude Code -- everyones' setup is different. You should experiment to see what works for you!
Hermes V1 will ship as the default in React Native 0.84 for both iOS and Android.
This means:
• 2-8% faster startup time
• 40%+ faster runtime
• faster Metro compilation (less Babel transforms)
Just landed in 0.84.0-rc.1
I'm Boris and I created Claude Code. Lots of people have asked how I use Claude Code, so I wanted to show off my setup a bit.
My setup might be surprisingly vanilla! Claude Code works great out of the box, so I personally don't customize it much. There is no one correct way to use Claude Code: we intentionally build it in a way that you can use it, customize it, and hack it however you like. Each person on the Claude Code team uses it very differently.
So, here goes.
If your R8 is configured with proguard-android.txt, you're missing out on optimizations.
Switching to proguard-android-optimize.txt offers a smaller apk, faster app startup times, and smoother runtime performance.
Change this one line and see the difference for yourself!
We know the pain of slow native builds… so we created something really awesome to fix them. 😎
Introducing RN Repo: a free, open-source plugin that makes shipping React Native apps faster thanks to prebuilt artifacts. ⚡️🚀
