I'm unable to API such as NSFileProviderManager on MacOS catalyst although the developer site says this extension is supported. https://developer.apple.com/documentation/fileprovider I've attempted to build a iOS framework to import into the catalyst target with no luck (I thought Catalyst was against the iOS API — maybe not?). Also attempted building a MacOS framework to import (maybe it's the other way around) but no luck. Has anyone found a workaround? Building for "MacOS for iPad" does work but isn't ideal for the UI.
