Solution: 

Suppose you are facing the crashing issue of react-native on iOS React Native app, then you can follow the below steps to solve the issue on your own.

Step 1: Check for Errors: Look for any error messages or stack traces in the Xcode console when the crash occurs. This can provide valuable clues about the cause of the crash.

Step 2: Update Dependencies: Ensure that react-native-restart and all other dependencies in your project are up to date. Sometimes, crashes can be caused by compatibility issues between different versions of libraries.

Step 3: Check Native Modules: If react-native-restart uses any native modules, make sure they are properly linked and configured in your Xcode project. Also, check if there are any conflicts with other native modules in your app.

Step 4: Permissions and Configuration: Verify that your app has the necessary permissions and configurations to restart itself programmatically. For iOS, ensure that you're not trying to restart the app in a restricted environment or in a way that violates Apple's guidelines.

Step 5: Testing Environment: Test the restart functionality on different iOS devices and simulators to see if the crash is consistent across all environments. This can help determine if the issue is specific to certain devices or configurations.

Step 6: Debugging: Use debugging tools such as Xcode's debugger or React Native Debugger to inspect the state of your app and identify any potential issues leading to the crash.

Step 7: Isolate the Issue: Try to isolate the crashing behavior by removing or commenting out other parts of your code that interact with react-native-restart. This can help narrow down the cause of the crash.

Step 8: Community Support: Search online forums, GitHub issues, and React Native community channels to see if other developers have encountered similar issues with react-native-restart. You may find helpful tips or solutions from the community.

Finally, if you're unable to resolve the issue on your own, consider reaching out to the maintainers of react-native-restart or seeking assistance from experienced React Native developers who may have encountered similar problems.

By following these steps and thoroughly investigating the potential causes of the crash, you should be able to diagnose and resolve the issue with react-native-restart in your iOS React Native app.
