Accessing iOS Address Book with Swift: array count of zero

Question

I am trying to write a simple method to ask a user for access to their address book and then print out the name of each person in the address book. I\'ve seen a number of tu

If anyone is also trying to get the email addresses of the contacts, I found that I needed to create two additional methods similar to the new one Wes showed.

Here's the updated version of the getContactNames() function:

 func getContactNames()
    {
        var errorRef: Unmanaged?
        addressBook = extractABAddressBookRef(ABAddressBookCreateWithOptions(nil, &errorRef))

        var contactList: NSArray = ABAddressBookCopyArrayOfAllPeople(addressBook).takeRetainedValue()
        println("records in the array \(contactList.count)")

        for record:ABRecordRef in contactList {
            var contactPerson: ABRecordRef = record

            var contactName: String = ABRecordCopyCompositeName(contactPerson).takeRetainedValue() as NSString
            println ("contactName \(contactName)")

            var emailArray:ABMultiValueRef = extractABEmailRef(ABRecordCopyValue(contactPerson, kABPersonEmailProperty))!

            for (var j = 0; j < ABMultiValueGetCount(emailArray); ++j)
            {
                var emailAdd = ABMultiValueCopyValueAtIndex(emailArray, j)
                var myString = extractABEmailAddress(emailAdd)
                println("email: \(myString)")
            }
        }
    }

And here are the two additional functions I created:

  func extractABEmailRef (abEmailRef: Unmanaged!) -> ABMultiValueRef? {
        if let ab = abEmailRef {
            return Unmanaged.fromOpaque(ab.toOpaque()).takeUnretainedValue()
        }
        return nil
    }

func extractABEmailAddress (abEmailAddress: Unmanaged!) -> String? {
    if let ab = abEmailAddress {
        return Unmanaged.fromOpaque(abEmailAddress.toOpaque()).takeUnretainedValue() as CFStringRef
    }
    return nil
}

Thanks again to Wes for his help on my initial question which helped me figure the above out.
