I’m building a React Native 0.72.10 iOS app and hitting build errors.
Environment:
macOS: Apple M4, Sequoia 15.7.2 Xcode: 26.1.1 React Native: 0.72.10
Errors:
Could not delete /Users/.../ios/build because it was not created by the build system
Unable to write file '/Users/.../ios/build/Pods.build/Debug-iphonesimulator/...': Operation not permitted (Multiple Pods / React Native framework headers affected)
What I’ve tried:
bash rm -rf ios/build rm -rf ~/Library/Developer/Xcode/DerivedData xattr -w com.apple.xcode.CreatedByBuildSystem true ios/build pod deintegrate && pod install sudo chown -R $(whoami) ios/build
Observations:
- ios/build is recreated automatically.
- Some files have com.apple.xcode.CreatedByBuildSystem: true.
3.Xcode have Full disk access authorisation.
Why does Xcode fail to delete / write to ios/build even though it’s recreated automatically by the build system?
Is this caused by Xcode itself, macOS permissions?
Any recommended fix or workaround for these “Operation not permitted” errors?
Thanks for the post, I am not familiar with the third party React Native.
You should check with the support resources provided by the 3rd party to get assistance with their software.
Unless another developer in the forums has experience with the third-party and can provide assistance.
My sole recommendation is to ensure that your macOS is updated to the most recent version, as well as your Xcode. Additionally, I suggest contacting React Native support to inquire if they have encountered similar issues.
Good luck.
