Getting to the Native in React Native
summary
Explains how native modules actually work: RCT_EXPORT_MODULE and RCT_EXPORT_METHOD enable a JavaScript call to invoke Objective‑C/Java that makes the phone vibrate; examples show callbacks, promises, events and exporting constants with no bridge roundtrip. Shows Swift and Kotlin setup (include bridging file or Gradle Kotlin plugin), how to inject initialProps on Android via a custom ReactActivityDelegate, and practical build fixes: Gradle dependency resolution, CocoaPods vs manual linking, and using react-native-scheme-manager to sync Xcode targets.
