如何在Mac OS X地址簿中访问有关联系人的信息？

Question

尝试在Mac上的地址簿中查找联系人时，会显示以下编译器错误“使用未解析的标识符'kABPersonFirstNameProperty'。”我找到了一个适用于iOS的示例here，但找不到与OS X等效的版本。根据文档，我已安装的OS X（10.10.5）版本中提供了ABRecordCopyValue。

if let book = ABAddressBook.sharedAddressBook() {
    let nameIsSmith = ABPerson.searchElementForProperty(kABLastNameProperty, label: nil, key: nil, value: "Smith", comparison: ABSearchComparison(kABEqualCaseInsensitive.rawValue))

    let peopleFound = book.recordsMatchingSearchElement(nameIsSmith)

    for person in peopleFound {
        let firstName = ABRecordCopyValue(book, kABPersonFirstNameProperty).takeRetainedValue() as? String
    }
}
