I'm trying to share data between my host app and apple watch extension with app group,and then it prints
Failed to read values in CFPrefsPlistSource<0x1567e3a0> (Domain: group.XXXXXXXXX, User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null)): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd
but it works well with my today extension in the same project.
Xcode Version 8.3.2 (8E2002)
