Using the new Contacts Framework in iOS 9, how can I get the contact creation date?
In previous versions, using the Address Book Framework, you could do:
ABRecordRef person = ...
NSDate *creationDate = (__bridge_transfer NSDate *)ABRecordCopyValue(person, kABPersonCreationDateProperty);
but using the new framework I didn't find any property on CNContact
nor any "key" to be able to get this value.
