更新一下，把相关操作写成了一个函数，添加了更多可读取的属性，文件在此：https://github.com/JoeMartini/SwiftContactFunction.git
求人不若求己，自己重写了相关方法，虽然还有问题，但是现在可以实现功能了

// ViewController.swift

import UIKit
import AddressBook
import AddressBookUI

class ViewController: UIViewController {
   override func viewDidLoad() {
        super.viewDidLoad()
        var testSwiftContacts:Array = getSysContacts()
        if testSwiftContacts.isEmpty {
            println("no contact")
        }
        for contact in testSwiftContacts {
            println(contact["FirstName"]!+"·"+contact["LastName"]!)
        }
    }
}

//  SwiftContactTool.swift

import Foundation
import AddressBook
import AddressBookUI

func getSysContacts() -> [[String:String]] {
    var error:Unmanaged<CFError>?
    var addressBook: ABAddressBookRef? = ABAddressBookCreateWithOptions(nil, &error).takeRetainedValue()

    let sysAddressBookStatus = ABAddressBookGetAuthorizationStatus()

    if sysAddressBookStatus == .Denied || sysAddressBookStatus == .NotDetermined {
        // Need to ask for authorization
        var authorizedSingal:dispatch_semaphore_t = dispatch_semaphore_create(0)
        var askAuthorization:ABAddressBookRequestAccessCompletionHandler = { success, error in
            if success {
                ABAddressBookCopyArrayOfAllPeople(addressBook).takeRetainedValue() as NSArray
                dispatch_semaphore_signal(authorizedSingal)
            }
        }
        ABAddressBookRequestAccessWithCompletion(addressBook, askAuthorization)
        dispatch_semaphore_wait(authorizedSingal, DISPATCH_TIME_FOREVER)
    }

    return analyzeSysContacts( ABAddressBookCopyArrayOfAllPeople(addressBook).takeRetainedValue() as NSArray )
}

func analyzeSysContacts(sysContacts:NSArray) -> [[String:String]] {
    var allContacts:Array = [[String:String]]()
    for contact in sysContacts {
        var currentContact:Dictionary = [String:String]()
        // 姓
        currentContact["FirstName"] = ABRecordCopyValue(contact, kABPersonFirstNameProperty)?.takeRetainedValue() as String? ?? ""
        // 名
        currentContact["LastName"] = ABRecordCopyValue(contact, kABPersonLastNameProperty)?.takeRetainedValue() as String? ?? ""
        // 昵称
        currentContact["Nikename"] = ABRecordCopyValue(contact, kABPersonNicknameProperty)?.takeRetainedValue() as String? ?? ""
        // 公司（组织）
        currentContact["Organization"] = ABRecordCopyValue(contact, kABPersonOrganizationProperty)?.takeRetainedValue() as String? ?? ""
        // 职位
        currentContact["JobTitle"] = ABRecordCopyValue(contact, kABPersonJobTitleProperty)?.takeRetainedValue() as String? ?? ""
        // 部门
        currentContact["Department"] = ABRecordCopyValue(contact, kABPersonDepartmentProperty)?.takeRetainedValue() as String? ?? ""
        //备注
        currentContact["Note"] = ABRecordCopyValue(contact, kABPersonNoteProperty)?.takeRetainedValue() as String? ?? ""
        allContacts.append(currentContact)
    }
    return allContacts
}

Swift现在已经开始投入使用了？？？

去这里找找看，
这里有一大票例子。
OC 跟swift 的转换应该差不多。
