只有选择一个联系人，如何使用ContactUI获得多个选择？

Question

所需:我试图在ContactsUI中选择以下多个联系人：

当前:我找不到一种方法来获取表视图单元格中的多个选择按钮

​

从下面的代码中可以看出，我使用的是contactPickerView，所以我不知道自己做错了什么:/

import UIKit
import ContactsUI
import Contacts


class FindContactsVC: UIViewController, CNContactPickerDelegate {

    //button to open contactUI
    @IBAction func contactsButton(_ sender: Any) {
        let cnPicker = CNContactPickerViewController()
        cnPicker.delegate = self    
        self.present(cnPicker, animated: true, completion: nil)  
    }

    //Works, but only allows me to select one at a time
    func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
        print(contact.phoneNumbers)
        print("WYASDFY")
    }

    //This function never runs :/
    func contactPicker(picker: CNContactPickerViewController, didSelectContacts contacts: [CNContact]){
       print(contacts)
        print("plz work!")
        contacts.forEach { contact in
            for number in contact.phoneNumbers {
                let phoneNumber = number.value 
                print("number is = \(phoneNumber)")
            }
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()       
    }
}

谢谢^^

我还没有检查代码的其他部分，但至少需要正确地实现第二个委托方法：

func contactPicker(picker: CNContactPickerViewController, didSelectContacts contacts: [CNContact]){

↓

func contactPicker(_ picker: CNContactPickerViewController, didSelect contacts: [CNContact]) {
