Error-03 Error while running project (IOS Specific)
No bundle URL present.

Encountering the "No Bundle URL Present" error is a common hurdle faced by React Native developers. This error typically occurs when attempting to run the application using
npx react-native run-ios/android without the Metro server being active. The Metro server is responsible for bundling JavaScript code and serving it to the mobile application.

  1. Start Metro Server:
    Ensure the Metro server is running before launching the application.
    Execute npm start in your project directory to start the Metro server.
  2. Specify Platform:
    i - run on iOS
    a - run on Android
    d - open Dev Menu
    r - reload app
  3. Troubleshoot Network:
    Ensure stable network connection or switch networks.
  4. Verify Configuration:
    Check metro.config.js for conflicts.
  5. Update Dependencies:
    Keep React Native and dependencies updated.
