Building v0 iOS and Fixing React Native Along the Way With Fernando Rojo, Szymon Rybczak & Oskar Kwaśniewski
About this episode
The episode discusses the development of Vercel's v0 iOS app using React Native, focusing on engineering challenges and solutions.
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.
