Moving an existing iPhone or Android app to React Native can be tricky. This guide helps you do it step by step. You can use Expo or bare React Native. Pick one path and follow the instructions.
First you check your app and choose a path. Then you run setup commands. Next you package React Native as a XCFramework for iOS or AAR for Android. Finally you add one screen at a time to your host app. This way you avoid rewriting everything at once.
The process uses a tool called @callstack/react-native-brownfield. It handles the tricky parts of mixing native code with React Native. You can migrate safely without breaking your existing app.
