You can debug Redux in React Native apps with help of the React Native Debugger tool: https://github.com/jhen0409/react-native-debugger/blob/master/docs/redux-devtools-integration.md

1) Make sure you got the React Native Debugger installed (https://github.com/jhen0409/react-native-debugger)

2) Enable JS Debugging in the running app (open development overlay via CTRL + M / CMD + M on Android devices, CMD + D on iOS devices)

3) Install the redux-devtools-extension package via npm install --save-dev redux-devtools-extension (https://www.npmjs.com/package/redux-devtools-extension)

4) Enable Redux debugging in your code:

import { createStore, applyMiddleware } from 'redux';
import { composeWithDevTools } from 'redux-devtools-extension';
 
const store = createStore(reducer, composeWithDevTools());

Important: Make sure you remove this code when building your app for production!

You'll see this approach in action in the Shop App course module ("Adding Items to the Cart" lecture)!
