Entering the UK, the Immigration Officer asks me what I do…
Me: Mobile Development
Him: You specialise in Swift or Kotlin?
Me: I mainly focus in RN
Him: What’s the point of RN these days with SwiftUI & Compose?
Me: 🤯
Not the conversation I was expecting at the border 😂

- Replying to @mo__javadTurns out he’s trying to launch an app on the side of his full time job! Power to him 🫡
- Replying to @mo__javadI guess this convo was prep for my talk tomorrow @cityjsconf… Looking forward to going over why NOT choosing React Native is the wrong bet in 2024! 🙌⚛️
- After playing about with SwiftUI a bit the last couple weeks, I was curious on how the render times compare to React Native & Flutter. I did a _very_ basic level test rendering 1000, 2000, and 3000 views with and without text. Here were the results:
- I've always wondered if not using StyleSheet in React Native would have a negative impact on your app's performance. I rendered 6000 views using: 1. `StyleSheet.create` 2. A regular object outside the component 3. Inlining styles 🤔 The results were interesting:
00:00 - My talk on why Airbnb was wrong to ditch React Native has been published on Youtube! 🎉 This was one of my favourite talks that I've done so far 🙌
- I've redone the experiments for React Native to use a more accurate measurement of the full render + paint on the UI thread. On average, there's ~30% drop in the measured render times, which gets it much closer to native performance. (Light red are the previous measurements)
- Replying to @AngryJoeShowBeen watching you since I was 12. Always enjoyed your gaming content, and even though I don’t game as much anymore, I still really enjoy your vids. Can’t wait for a political AJ vid! 😁
- FlatList slows down React Native apps. 🐌 This is nothing new, but when targeting lower-spec devices, such as TVs, you've got to be super careful. Our team built a specific carousel/list component for TVs, and it lowers CPU usage by around 25% compared to FlatList 🤯🏎️
- Super excited to announce the launch of the React Native TV Blog! 🎉📺 Using RN on the big screen has long been underserved - there wasn't a single, unified resource where devs can go to learn about how to build TV apps with RN. We've been working on TV apps for years!
- I've been toying with the idea of creating microfrontends in mobile apps. I wanted to try to have two separate bundles in a single app that could have OTAs trigger updates separately from one another. I was able to get a (very very) rough POC showing this working:
