Trying to add an `NSSharingServicePickerToolbarItem` to the NStoolbar of my scene's window, but when I set the `NSSharingServicePickerToolbarItem`'s activityItemsConfiguration to a class that implements `UIActivityItemsConfigurationReading` I get -[MYAPP.MYCLASS _uinsApplicationActivityProxies]: unrecognized selector sent to instance 0x6000026331e0
I'm not exactly sure how I can satisfy this unrecognized selector given it appears to be for a private method. Thoughts?
We're encountering the same issue. Does the class that implements UIActivityItemsConfigurationReading need to be of a certain type?
