IOS 9 - how to get contacts by change date?

Question

We are developing an iOS 9 application using the new one Contacts Framework. This application sends user contacts to our address (after approval). We are dealing with huge contact lists (> 3000), and we would only like to send updated contacts.

The old API (ABPerson and co) had this property: kABPersonModificationDateProperty.

But I can’t find the equivalent in the new one Contacts Frameworkin iOS 9. I looked at CNContactStoreDidChangeNotification, but we want to capture the changes that have occurred even when our application is closed.

Does anyone know how to filter your contact list by change date or any suitable solution?

Thanks a lot!

Change . I tried using ABAddressBook, ABPersonand kABPersonModificationDateProperty, and I get the modification dates of the contacts with a warning for using outdated code. So another option
