Swift: установить адрес свойства ABRecord

Question

Я взглянул на вопрос SE здесь [ответ Avinash] и ресурс Apple здесь [внизу страницы 18 и вверху страницы 19], пытаясь задать адрес для ABRecord, Я сделал все возможное, чтобы перевести их из Objective-C, но, видимо, я где-то допустил ошибку, так как на линии let dict = CFDictionaryCreate(kCFAllocatorDefault, keys, values, 5, &kCFCopyStringDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks) Я получаю ошибку Cannot assign to immutable value of type 'CFDictionaryValueCallBacks',

Вот мой код:

    let information: ABRecord = ABPersonCreate().takeRetainedValue()

    let address: ABMutableMultiValueRef = ABMultiValueCreateMutable(ABPropertyType(kABMultiDictionaryPropertyType)).takeUnretainedValue()

    var keys = [CFStringRef]()
    var values = [CFStringRef]()

    keys.append(kABPersonAddressStreetKey)
    keys.append(kABPersonAddressCityKey)
    keys.append(kABPersonAddressStateKey)
    keys.append(kABPersonAddressZIPKey)
    keys.append(kABPersonAddressCountryKey)
    keys.append(kABPersonAddressCountryCodeKey)

    Note: country code left out

    values.append(s["kABPersonAddressStreetKey"]!! as NSString)
    values.append(s["kABPersonAddressCityKey"]!! as NSString)
    values.append(s["kABPersonAddressStateKey"]!! as NSString)
    values.append(s["kABPersonAddressZIPKey"]!! as NSString)
    values.append(s["kABPersonAddressCountryKey"]!! as NSString)
    values.append(s["kABPersonAddressCountryCodeKey"]!! as NSString)

    let dict = CFDictionaryCreate(kCFAllocatorDefault, keys, values, 5, &kCFCopyStringDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks)

    let scanned = ABUnknownPersonViewController()

    let identifier = ABMultiValueIdentifier()

    ABMultiValueAddValueAndLabel(address, dict, kABHomeLabel, &identifier)

    ABRecordSetValue(information, kABPersonAddressProperty, address, nil)

Я уверен, что есть гораздо более краткий способ сделать это, но вот решение, которое я придумал.

 var addressComponents = [String : String]()

    if let value = s["kABPersonAddressStreetKey"] {
        addressComponents[kABPersonAddressStreetKey as String] =  value
    }

    if let value = s["kABPersonAddressCityKey"] {
        addressComponents[kABPersonAddressCityKey as String] = value
    }

    if let value = s["kABPersonAddressStateKey"] {
        addressComponents[kABPersonAddressStateKey as String] = value
    }

    if let value = s["kABPersonAddressZIPKey"] {
        addressComponents[kABPersonAddressZIPKey as String] = value
    }

    if let value = s["kABPersonAddressCountryKey"] {
        addressComponents[kABPersonAddressCountryKey as String] = value
    }

    if let value = s["kABPersonAddressCountryCodeKey"] {
        addressComponents[kABPersonAddressCountryCodeKey as String] = value
    }

    let address: ABMutableMultiValue = ABMultiValueCreateMutable(ABPropertyType(kABMultiStringPropertyType)).takeRetainedValue()
    ABMultiValueAddValueAndLabel(address, addressComponents, kABHomeLabel, nil)
    ABRecordSetValue(information, kABPersonAddressProperty, address, nil)
