AI is making app development faster, but it is also changing the tradeoffs. React Native used to win on speed and shared code. With AI now able to write and convert code across platforms, that advantage is less obvious. In this talk, we test this by building the same app in React Native and in Swift, then using agents to convert it to Kotlin. The goal is to see where React Native still works well, where it struggles, and what this means for teams choosing how to build their apps.
