Run this demo app:

$ npm install
$ npx pod-install
$ npx react-native run-ios

More info about react native setup: https://reactnative.dev/docs/environment-setup?guide=native&platform=ios

The code of the SDK can be added in ios/MyCustomNativeCode/MyCustomNativeCode.swift. When adding new functions, make sure to add them to the bridge as well in ios/MyCustomNativeCode/MyCustomNativeCode.m. I have added an example function called getMyCustomNativeMessage() which can be called in React Native. See src/bridge.tsx for an example on how to call the bridge functions.

So:

1. Add code to ios/MyCustomNativeCode/MyCustomNativeCode.swift
2. Add funcs to bridge to ios/MyCustomNativeCode/MyCustomNativeCode.m
3. Call the funcs in src/bridge.tsx

Note that Build Libraries for Distribution is set to NO. Switching it to yes will result in errors during the build process.

We prefer to try a local pod, but we are happy with whichever integration method works!
