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/Xcode6-Beta3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift 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{
      return
    }

    /* Get all the phone numbers this user has */
    let unmanagedPhones = ABRecordCopyValue(person, kABPersonPhoneProperty)
    let phones: ABMultiValueRef =
    Unmanaged.fromOpaque(unmanagedPhones.toOpaque()).takeUnretainedValue()
      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

      println(phone)
    }  
}

In case someone is looking for a final way to deal with ABRecords in Swift 2, here it is:

func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController, didSelectPerson person: ABRecord) {

    let firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty).takeRetainedValue()
    let lastName = ABRecordCopyValue(person, kABPersonLastNameProperty).takeRetainedValue()

    var emails:[String] = []
    let emailRecords = ABRecordCopyValue(person, kABPersonEmailProperty).takeRetainedValue() as ABMultiValueRef
    let emailsCount = ABMultiValueGetCount(emailRecords)
    for index in 0 ..< emailsCount {
        if let email = ABMultiValueCopyValueAtIndex(emailRecords, index).takeRetainedValue() as? String {
            emails.append(email)
        }
    }

    print("Contact selected. firstName: \(firstName), lastName: \(lastName), emails: \(emails)")

}
