Resolving the ‘event2/event-config.h’ File Not Found Error in iOS React Native Projects

17 December 2024 Stephan Petzl Leave a comment Tech-Help

When developing a React Native application for iOS, encountering the 'event2/event-config.h' file not found error can be a roadblock, especially when dealing with Flipper integration. This guide will walk you through the steps to resolve this issue effectively.

Understanding the Issue

This error typically arises due to compatibility issues with the Flipper version used in your project. Flipper is a platform for debugging mobile apps, and its integration into React Native projects can sometimes lead to conflicts, especially with iOS builds.

Steps to Resolve the Issue

1. Update Flipper Version

Flipper frequently updates to support new features and device architectures. Ensure you are using the latest version. Follow these steps:

• Determine the latest Flipper version by running npm info flipper.
• Update your Podfile to use the latest version. For instance, use use_flipper!({ 'Flipper' => '0.95.0' }).
• Navigate to the iOS directory and run pod install to apply the changes.

2. Flipper Folly Version Check

If you continue to face issues, ensure that the Flipper-Folly version is specified correctly in your Podfile:

• Modify your Podfile to include use_flipper!({ 'Flipper-Folly' => '2.3.0' }).
• Run pod update or pod install to ensure all dependencies are up to date.

3. Clean and Rebuild the Project

After making these changes, clean and rebuild your project:

• Delete the Podfile.lock and ./Pods/ directory.
• Run pod repo update followed by pod install.
• Build your project again using Xcode.

Troubleshooting Further

If you are using an M1 chip-based Mac, ensure that Xcode is set to open using Rosetta. This can sometimes resolve build issues related to architecture compatibility.

Leveraging Repeato for Automated Testing

Once your build issues are resolved, consider using Repeato, our no-code test automation tool for iOS and Android, to streamline your testing process. Repeato uses computer vision and AI to quickly create, run, and maintain automated tests, which can be especially useful for ensuring your app functions correctly after resolving such issues.

By integrating Repeato into your workflow, you can efficiently manage your testing needs without delving into complex coding, making it a valuable addition to your React Native development toolkit.
