To debug a React Native app that fails to launch, start the Metro bundler first to prevent port conflicts, then use custom npm or yarn scripts to build and install the app on iOS simulators or Android emulators while checking project configurations.

React Native iOS builds fail with CocoaPods errors when native dependencies change. Reset caches, reinstall pods correctly using the appropriate iOS workspace, and rebuild to resolve the installation failures and clear the build state.

The best way to prevent Metro bundler port conflicts is using a Metro-first workflow. Start Metro safely to ensure it reaches the expected port, validate its reachability, and confirm the app connects to the correct running instance before launching.

To inspect runtime logs and component trees in a React Native simulator, use purpose-built agent tools after a successful build. These tools evaluate JavaScript, capture screenshots, inspect logs, and control devices while reloading the app.

Yes, you can run unit and E2E tests using this React Native debugging workflow. The workflow directs you to the right tools to execute tests using the project's existing configurations when they are properly set up.

When React Native build errors persist after clearing the cache and reinstalling pods, stop guessing and ask for clarification. The workflow advises checking custom package scripts and validating Metro reachability before proceeding.
