Brownfield development allows teams to adopt React Native gradually, embedding it into production apps one screen at a time.

In this walkthrough, Burak Güner (https://x.com/_atlj) shows how to:
• Spin up a Rock (formerly known as React Native Enterprise Framework, or shortly RNEF) project configured for iOS
• Export React Native modules as XCFrameworks
• Import and initialize React Native in a SwiftUI app
• Replace a native view with a React Native screen

By the end, you’ll understand how to extend an existing iOS app with React Native in a controlled, incremental way.
