Encountering the error message Print: Entry, ":CFBundleIdentifier", Does Not Exist can be frustrating when working with React Native and Xcode. This error typically indicates an issue with your project’s configuration, often related to the build path or missing configuration files. In this guide, we will explore effective solutions to resolve this error and get your iOS application running smoothly.
Understanding the Error
When you run react-native run-ios, the build process may succeed, but the installation of the app on the simulator or device fails, resulting in the error mentioned. This issue is often due to incorrect paths or missing configuration files, such as the Info.plist, which holds the CFBundleIdentifier.
Step-by-Step Solutions
Solution 1: Adjust Build Settings in Xcode
One of the most effective solutions involves adjusting the build settings in Xcode:
- Open your project in Xcode.
- Navigate to File > Project Settings.
- Click the Advanced button.
- Select “Custom” and choose “Relative to Workspace” in the dropdown menu.
- Change the paths for “Build/Products” to “build/Build/Products” and “Build/Intermediates” to “build/Build/Intermediates”.
- Click Done to save your changes.
Solution 2: Update Project Dependencies
Sometimes the error is due to outdated dependencies. Follow these steps to update:
- Remove the
node_modulesfolder andyarn.lockfile: - Reinstall your dependencies:
rm -rf node_modules yarn.lockyarn installSolution 3: Switch to Legacy Build System
If you are using Xcode 10 or later, switching to the legacy build system may resolve the issue:
- Open your project in Xcode.
- Go to File > Project Settings.
- Under Build System, select Legacy Build System from the dropdown menu.
Additional Considerations
If none of the above solutions work, consider checking the following:
- Ensure that your Info.plist file is correctly configured with a valid
CFBundleIdentifier. - Check for any white spaces in the project directory path, as they can lead to errors.
- Ensure that all paths and configurations are consistent with your project’s requirements.
