Building v0 iOS and Fixing React Native Along the Way With Fernando Rojo, Szymon Rybczak & Oskar Kwaśniewski

Vercel’s v0 iOS app is built with React Native, but it looks and feels like a fully native iOS product.

In this episode of React Universe On Air, we go deep into how the v0 mobile app was built: from choosing Expo and going iOS-first, to writing native modules, fixing low-level React Native issues, and upstreaming improvements back to the ecosystem. This is a hands-on engineering conversation with Fernando Rojo, Szymon Rybczak, and Oskar kwaśniewski about real trade-offs, real constraints, and what it takes to ship a polished app under real deadlines.
