Extract metadata MXF files

I'm trying to read meta information from MXF files without success. I get an empty AVAsset array.

I saw that there are mentions of "MTRegisterProfessionalVideoWorkflowFormatReaders". But there is absolutely no documentation. I don't know where to look. Has anyone encountered this? Please help with any information

When in doubt, check the framework header directly, you can find the one you want in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/MediaToolbox.framework/Versions/A/Headers/MTProfessionalVideoWorkflow.h
