Am I correct that with a address book permission we should be able to pretty reliably get a users phone number if they have given address book permissions via the new "My Card" contact that seems to be automatically added to your addressbook when you download IOS9?
I always wanted to do a find friends but i did not want to force users to type/verify their number....this seems to be a solid work around for ios9 users.

I am currently dealing with the same issue but unfortunately it seems that this is not possible according to Apple.
