I have a file based iOS app and I'm using a UIActivityViewController to present various activities, like printing and copying the file as plain text.
An "Add People" button has started appearing in the share sheet. When I tap it, my app crashes:
*** Assertion failure in -[_UICloudSharingActivity performActivity], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3698.54.4/_UICloudSharingActivity.m:195
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Should never be called'
I'd like to supress this button, but I can't find the correct key to assign to UIActivityViewController's excludedActivityTypes. None of the UIActivityType's listed in the header correspond to sharing with other people.
Alternatively, I could just implement whatever is necessary for this to work, but I can't find it documented anywhere what this button even actually does, or what is required of me to make it work.
