AddressBook: ABRecordCopyValue(person, kABPersonPhoneProperty) failing to get some numbers

Question

After much searching, I'm stuck with a problem that (I believe) hasn't been clearly addressed.

My goal is to pull phone numbers from the phone's contact list. Permission has already been granted. I use this bit of code to extract data from a given contact (variable 'person'):

let unmanagedPhones: ABMultiValueRef = ABRecordCopyValue(person, kABPersonPhoneProperty).takeUnretainedValue()
println("unmanagedPhone: \(unmanagedPhones)")

For some of the contacts on my phone, this returns the following (I've censored some of the numbers with #'s):

unmanagedPhone: ABMultiValueRef 0x170468d00 with 2 value(s) 0: $!Mobile!$ (0x#########) - 1 (###) ###-#### (0x170#45###) 1: $!Work!$ (0x#########) - 1 (###) ###-#### (0x#70##3#a0)

For many others, though, this returns:

unmanagedPhone: ABMultiValueRef 0x170474a40 with 0 value(s)

I've confirmed that the contacts in question do have at least one number. In exploring the address book, I can't figure out why some contacts work and others don't. Does anyone have any advice or direction as to how to begin to debug this? Thanks, all!

Try this:

let unmanagedPhones = ABRecordCopyValue(person, kABPersonPhoneProperty)

    //check to make sure we have phone numbers or we will get Fatal error
    if unmanagedPhones != nil {

        let phones: ABMultiValueRef = unmanagedPhones.takeUnretainedValue() as ABMultiValueRef
        let allPhones = ABMultiValueCopyArrayOfAllValues(phones).takeRetainedValue() as NSArray

        for eachPhone in allPhones{
            print(eachPhone)
        }
    }
    else {
        println("No phone numbers found")
    }
