Prerequisites
- I have read and followed every applicable step in the Nitro Modules Troubleshooting guide.
- I have read the VisionCamera Troubleshooting guide and Installation guide.
- I did a clean build — deleted
node_modules,ios/Pods,ios/build, and Xcode's DerivedData, then reinstalled. - I searched existing build-error issues and found nothing matching.
Full build error output

Additional context
Installing react-native-vision-camera-barcode-scanner seems to cause some problem in xcode scheme, making it impossible to build for simulator on iOS 26. I've tested on iOS 18.6 and android, works perfectly. If i remove the package, works too.
I didn't try to build for physical device.
Submission
- I pasted the full error output as text (not a screenshot).
- I wrote this report in my own words. I did not paste AI-generated summaries of the error.
- The reproduction repository I linked is public and reproduces the build error on a fresh clone. I understand the issue will be closed without one.
