Using the new Contacts Framework in iOS 9, how can I get the contacts' creation date?
In previous versions, by using the Address Book Framework, I could do this:
ABRecordRef person = ...
NSDate *creationDate = (__bridge_transfer NSDate *)ABRecordCopyValue(person, kABPersonCreationDateProperty);
but I couldn't find the right way to do it using the new framework, there is no obvious property in CNContact
nor any relevant key.
