iOS: equivalence for migration AddressBook to Contact framework

Question

I'm migrating from AddressBook to Contact Framework in iOS 9, and encountered a few issues, could someone with similar experience share some opinions?

1. ABAddressBookCreateWithOptions

Is it the same as creating a new CNContactStore instance?

2. ABRecordCopyCompositeName

What's the equivalent method in contact framework? From its documentation, it returns:

For person records: The concatenated value of these properties: Prefix, Suffix, Organization, First name, and Last name.

But I couldn't find an equivalent way of getting the same information from contact store?

3. ABAddressBookCopyLocalizedLabel

Is it the same as calling labeldValue.value.stringValue?

Thanks!
