Hi

Mobile scanner works properly on android, but on IOS(18.0.1) physical device throws this error:

**"Library/Developer/Xcode/DerivedData/Runner-czitbbrlbqgugmapfcauuxbvputn/Build/Products/Release-iphoneos/mobile_scanner/mobile_scanner.framework/Headers/mobile_scanner-Swift.h:342:31: 'objc_ownership' only applies to Objective-C object or block pointer types; type here is 'CVPixelBufferRef Nullable' (aka 'struct __CVBuffer *')"**_

This should only be a warning, we had this error on the MacOS implementation before.

Is this a fatal error in iOS 18, when building on physical devices?
I see you are using a very old version of mobile_scanner, though.
Does this happen on version 6.0.0 ?
