@aboutrc @expo Did you post an issue about this? There is a fix in RN for a TurboModule NSException that isn't yet released - could it be related? github.com/facebook/react… It should not be about `EAS_USE_PRECOMPILED_MODULES` - this should be unrelated. (famous last words)

Hours trying to get a map working in @expo on iOS 26. Tried Apple Maps — crash. Switched to a WebView — crash. iOS 26 + Expo SDK 55's New Architecture has a TurboModule bug that kills any app using native components in distribution builds? Works perfectly on my machine. Ships broken every time.

Seeing agents fail like this when asked to create an avatar from my profile picture makes me believe I’ll have a job next year as well.

Expo Agent looks really promising. Building cool apps with React Native isn't what it used to be.

@tmikov Agree with you. Although I'm still trying to use coding without an LLM as a mediative thing to relax and focus on a single problem.

At this point, if you don't know that "coding" is over, then you are delusional. There is no more coding. I don't know what that means in the long term, but for now, it is over, done. I am not happy about it. Just reporting.

I've been a single-monitor (single but big) for many years. Now that I've started using multiple agents working different tasks I can see that multiple monitors might be a thing. 🤔

I very rarely see Claude responding with any sort of aggression - but today it actually protested loudly! I just asked it why it would run a certain command and then...:

This has been quite a journey! I remember @terrysahaidak and I discussing running JavaScript in the UI thread in Reanimated 1.0 — with a PR demonstration here: github.com/software-mansi…. Then came Reanimated 2.0, I created react-native-worklets-core as an alternative execution engine with @mrousavy - and now we have a separate, focused worklets library we all love. Epic to have been a part of it.

Even though Claude/Opus 4.5 can fix almost anything - it still has problems solving precompiling modules on iOS when you mix Objective-C, Swift and C++. Nice to know that I'm still valuable at least when it comes to build issues🏗️

This is something I still feel I’ve never mastered 100%. Thanks to @amanhimself for making it clear!
Expo@expo

Native iOS large titles are one of those tiny details that make an app feel like it truly belongs on an iPhone. In this Expo Router tutorial @amanhimself walks through how to: ♢ Enable headerLargeTitle in your stacks ♢ Handle blur behavior on iOS 18 vs 26 ♢ Keep Android headers readable with conditional options If you want your Expo Router navigation to feel like Settings or Messages, this one is for you: amanhimself.dev/blog/large-hea…
