Hi everyone,

I'm encountering a persistent issue when trying to build my React Native project for iOS. I'm using the react-native-vision-camera library (version 4.6.4) and I've set my iOS deployment target to 16.0 in the app.json file. Despite this, the build process fails with an error related to the react-native-vision-camera pod, which seems to be stuck on an older version (2.15.4) that requires a different C++ version and a lower deployment target.

Here's what I've tried so far:

Ensured that the C++ version is set to 17 as required.

Cleared and reinstalled all pods (rm -rf ios/Pods ios/Podfile.lock followed by pod install).

Confirmed that the deploymentTarget in the app.json is set correctly to 16.0.

However, the error persists and the build continues to fail, pointing to a compatibility issue with the react-native-vision-camera pod. I'm not sure if there's a cache issue or a configuration step I'm missing.

Environment:

React Native version: 0.76.7

react-native-vision-camera version: 4.6.4

iOS deployment target: 16.0

Expo SDK version: 52.0.40

Attached: app.json, eas.json, package.json, and the error log screenshot.

Any insights or suggestions from the community or Apple engineers would be greatly appreciated. Thank you!

Nothing in your attachments gives me more info on the error around this. Xcode 16.4 beta resolves an issue with C++ that might be related, but I can't be sure without the info from your logs. Here's what the release note says so you can determine if this is your C++ issue or not:

Fixed: The base template for std::char_traits is restored after being removed in Xcode 16.3; it is still deprecated and is going to be removed in a future release. Restoring the base template allows code that attempts to instantiate char_traits with types that are not provided by the Standard (for example, std::basic_string<long long> and similar) to still compile, giving it more time to transition.  (149025504)
