Troubleshooting the Maximum Call Stack Size Exceeded Error in React Native on iOS 13+

If you've recently been developing or maintaining a React Native application, you might have encountered the frustrating error: Maximum call stack size exceeded. This commonly occurs when you're trying to run your app on iOS simulators, particularly on versions 13 and above. In this guide, we’ll explore the potential reasons behind this error and provide actionable steps to resolve it.

Understanding the Problem

When running your React Native app on older iOS simulators, such as those earlier than version 13, everything might seem to work perfectly. However, if you find yourself stuck with the splash screen followed by the Maximum call stack size exceeded error on iOS 13.5 or newer versions, it indicates that there's an issue with either the code or the way React Native components are being handled in the new environment.

The error often traces back to the require.js file where modules are loaded. You might notice that a significant number of components are being loaded in older iOS versions compared to newer ones, which could lead to issues in memory or circular references.

Steps to Diagnose and Fix the Issue

While troubleshooting can seem daunting, breaking down the process into manageable steps can substantially ease the effort. Below are some recommended actions to help pinpoint the problem and implement a solution.

1. Investigate the app.js File

The first place to begin diagnosing your issue is in your app.js file. This file often serves as the central hub of your application. Here's how you can systematically investigate it:

Comment Out Code: Start by commenting out all code within the app.js file.

Gradual Reintroduction: Gradually uncomment sections of the code to see if the issue persists after adding each part back. This method helps isolate the section causing the error.

2. Upgrade React Native

Upon reviewing the React Native version you're using, it's important to note that react-native 0.59.9 may not have optimal support for iOS 13+ . Consider upgrading to 0.60.0 or newer. However, be aware that this upgrade might require significant changes in your project configuration. Be sure to:

Check the Compatibility: Read through the release notes for each version of React Native to understand the breaking changes that might impact your app.

Test Incrementally: Begin with small upgrade steps before jumping to the latest version, which would allow you to effectively manage any issues that arise.

3. Assess All Dependencies

You mentioned using react-native-device-info version 5.6.2; ensure that all dependencies are compatible with your current React Native version. Here’s what you can do:

Update Dependencies: Consider updating all your dependencies, especially if you plan on upgrading React Native itself. Using outdated libraries can cause conflicts and lead to errors.

Review Dependency Documentation: Some libraries may have specific compatibility requirements that could help avoid the issues you're facing.

4. Utilize Debugging Tools

Don’t shy away from employing debugging tools to gain deeper insights into where things might be going wrong. Consider using:

Debug Statements: Add logging to different parts of your code to identify the flow and where the stack size exceeds its limit.

React Native Debugger: Leverage the built-in debugging tools available for React Native which can give you real-time performance and memory metrics.

Conclusion

Addressing the Maximum call stack size exceeded error in your React Native app can be a challenging process, especially when moving to newer versions of iOS. However, by methodically investigating your cod
