What's the iOS < 9 alternative to CNLabeledValue?

Question

I have implemented both the framework for Contact and AddressBook in order to fetch contacts from the contact book for users both above and below iOS 9. In order to press a row to access another view to see the contact information I have used CNLabeledValue in didSelectRowAt like this:

if #available(iOS 9.0, *) {
    switch((number as! CNLabeledValue<CNPhoneNumber> ).label){
        case CNLabelPhoneNumberMobile:phoneContact?.mobilePhone = (number as! CNLabeledValue<CNPhoneNumber>).value.stringValue
        case CNLabelPhoneNumberiPhone:phoneContact?.mobilePhone = (number as! CNLabeledValue<CNPhoneNumber>).value.stringValue
        case CNLabelPhoneNumberMain:phoneContact?.mobilePhone = (number as! CNLabeledValue<CNPhoneNumber>).value.stringValue
        case CNLabelHome:phoneContact?.homePhone = (number as! CNLabeledValue<CNPhoneNumber>).value.stringValue
        case CNLabelWork:phoneContact?.workPhone = (number as! CNLabeledValue<CNPhoneNumber>).value.stringValue
        default:phoneContact?.mobilePhone = (number as! CNLabeledValue<CNPhoneNumber>).value.stringValue
        }
} else {
   // Fallback on earlier versions

   }

The ContactBook code works, but what was used before CNLabeledValue before iOS 9? Is there a framework to use?

Answer 1

The Contacts framework (CN*) was added in iOS 9. Before that, we used the AddressBook framework. There is no exact equivalent to CNLabledValue there. The closest is ABMultiValue, which is a CoreFoundation type.

Note that the current docs often suggest that some of these types only exist in macOS 12+, but that's not correct. Many of these did exist on older versions of iOS.
