Accessing iOS Address Book with Swift: array count of zero

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 tutorials explaining how to do this in objective-C, but am having a hard time converting them to swift.

Here’s what I’ve done so far. The below block runs in my viewDidLoad() method and checks to see whether the user has authorized access to the address book or not, if they have not authorized access yet, the first if-statement will ask for access. This section works as expected.

var emptyDictionary: CFDictionaryRef?
var addressBook: ABAddressBookRef?
if (ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.NotDetermined)
{
println("requesting access...")
addressBook = !ABAddressBookCreateWithOptions(emptyDictionary,nil)
ABAddressBookRequestAccessWithCompletion(addressBook,{success, error in
if success {
self.getContactNames();
}
else
{
println("error")
}
})
}
}
else if (ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.Denied || ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.Restricted)
{
println("access denied")
}
else if (ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.Authorized)
{
println("access granted")
getContactNames()
}

Once I know the user has granted access, I run the getContactNames() method which is below. After much back and forth, I was finally able to get this to compile by adding the takeRetainedValue() method in order to convert the array returned by ABAddressBookCopyArrayOfAllPeople from an unmanaged array to a managed array, this then allows me to convert the CFArrayRef to an NSArray.

The issue I’m running into is that the contactList array ends up having a count of 0 and the for loop therefore gets skipped. In my simulator, the address book has 6 or 7 records, so I would expect the array to be of that length. Any ideas?

func getContactNames()
{
addressBook = !ABAddressBookCreateWithOptions(emptyDictionary,nil)
var contactList: NSArray = ABAddressBookCopyArrayOfAllPeople(addressBook).takeRetainedValue()
println("records in the array \(contactList.count)") // returns 0
for record:ABRecordRef in contactList {
var contactPerson: ABRecordRef = record
var contactName: String = ABRecordCopyCompositeName(contactPerson).takeRetainedValue()
println ("contactName \(contactName)")
}
}

One additional point – if I use the ABAddressBookGetPersonCount method, it returns -1.

 var count: CFIndex = ABAddressBookGetPersonCount(addressBook);
println("records in the array \(count)") // returns -1

Based on this link ABAddressBookGetPersonCount returns -1 in iOS, it seems that this function returning -1 could be related to permission not being granted, but I definitely have asked for permission in the code above (and granted it when I run the app in the simulator)
