The sharing of the address book using the default Apple method (not my method below) is good: But, for now, it’s not really meant for sharing between different people. I figure Apple will solve this problem eventually by changing the way the address book works. I’ve gotten a lot of questions about this lately. But, it doesn’t share address books well, at least not yet. NOTE: “Apple Family Sharing” is good for sharing the in-app purchases, iTunes, iBooks, and iCloud storage.
