I am developing a File Provider Extension on Mac. I am confused about how the extendedAttributes property works. The property never seems to be populated with any extended attributes.
I've tried setting some custom extended attributes on my documents in testing, but they are never populated in the itemTemplates that are produced in the extension. The dictionary that would hold the extended attributes always is empty.
I began to think that it only supported Mac-created attributes such as com.apple.quarantine.
I then tried importing some files that are 'quarantined' with this appropriate extended attribute but still have not seen this data appear in my extension either.
Any clarity here with what I should be expecting or what I should try would be helpful.
