Swift (iOS 8 SDK) Convert Unmanaged<ABMultiValueRef> to ABMultiValueRef

I need to convert the return value of this function from the AddressBook framework:

ABRecordCopyValue(nil, kABPersonPhoneProperty)

to a value of type ABMultiValueRef

This function is currently marked as this:

func ABRecordCopyValue(record: ABRecordRef!, property: ABPropertyID) -> Unmanaged<AnyObject>!

So I can convert it to Unmanaged like so:

ABRecordCopyValue(person, kABPersonPhoneProperty) as Unmanaged<ABMultiValueRef>

But then how can I get it as an ABMultiValueRef so that I can pass it to this function?

func ABMultiValueGetIndexForIdentifier(multiValue: ABMultiValueRef!, identifier: ABMultiValueIdentifier) -> CFIndex

I did this:

let managedPhones = Unmanaged.fromOpaque(phones.toOpaque()).takeUnretainedValue() as ABMultiValueRef

And I keep getting this compiler error:

Bitcast requires both operands to be pointer or neither
%89 = bitcast %objc_object* %88 to %PSs9AnyObject_, !dbg !325
LLVM ERROR: Broken function found, compilation aborted!
Command /Applications/ failed with exit code 1


I found the solution:

func peoplePickerNavigationController(
  peoplePicker: ABPeoplePickerNavigationController!,
  didSelectPerson person: ABRecordRef!) {

    /* Do we know which picker this is? */
    if peoplePicker != personPicker{

    /* Get all the phone numbers this user has */
    let unmanagedPhones = ABRecordCopyValue(person, kABPersonPhoneProperty)
    let phones: ABMultiValueRef =
      as NSObject as ABMultiValueRef

    let countOfPhones = ABMultiValueGetCount(phones)

    for index in 0..<countOfPhones{
      let unmanagedPhone = ABMultiValueCopyValueAtIndex(phones, index)
      let phone: String = Unmanaged.fromOpaque(
        unmanagedPhone.toOpaque()).takeUnretainedValue() as NSObject as String
