I have a feeling most of the recent app rewrites are like this. Write it from scratch, leave all the technical debt and bad patterns behind, and suddenly it feels like the most responsive app on your phone. Not really a technology problem, more that agents just write better code than we do.

The numbers behind that third line. iPhone 16 Pro, iOS 27, Release build, 100,000 calls. And to be fair: much of the SDK 57 work sped up the 1.0 API too. Existing modules got faster with no code change 🚀

I've wanted this API for years. Turns out that's what agents want too 🤖 Expo Modules 2.0 🎉 → a module is just an annotated Swift class → agents write it with almost nothing in context → up to 14.5× faster calls than SDK 55 Early look, iOS first 👇
