Have I written custom code (as opposed to using a stock example script provided in MediaPipe)

No

Task name (e.g. Image classification, Gesture recognition etc.)

MediaPipeTasksVision

Programming Language and version (e.g. C++, Python, Java)

Build fails with 346 duplicate symbols.

Describe the expected behaviour

Build succeeds.

Standalone code/steps you may have used to try to get what you need

Other info / Complete Logs

In the image_classification example add:
pod 'OpenCV-Dynamic-Framework'
to the Podfile.
Then try to build in Xcode and get:
duplicate symbol '_OBJC_CLASS_$_MatOfPoint3f' in:
    /Users/howardgood/Library/Developer/Xcode/DerivedData/ImageClassifier-dkioidhfgemwblbcqjglkdhicnlo/Build/Products/Debug-iphoneos/XCFrameworkIntermediates/MediaPipeTasksCommon/MediaPipeTasksCommon.framework/MediaPipeTasksCommon[1628](MatOfPoint3f.o)

etc. etc.

MediaPipeTasksCommon xcframework should hide its public symbols like TensorFlowLite xcframework does:
