iOS Brownfield App With React Native in an Easy Way

A step-by-step guide to integrating React Native into an existing native iOS app (brownfield approach). Covers the manual setup using RCTBridgeDelegate, RCTBridge, and RCTRootView, then introduces the react-native-brownfield package as a simpler alternative. The package provides a cleaner API for starting the React Native runtime and exposes JS-callable methods to handle native back gestures and navigation pop behavior, solving common navigation issues in brownfield setups.
