iOS Swift CNContactPickerViewController search contact and add to selection

The search results seem to be working in single selection mode only, so make sure you implement

func contactPicker(CNContactPickerViewController, didSelect: CNContact)

only, but not

func contactPicker(CNContactPickerViewController, didSelect: [CNContact])

If you implement both, the version wich takes only one CNContact as argument is ignored and the multi selection mode is used instead.

Use this updated code and  


   @IBAction func AddBtnKlkFnc(sender: AnyObject)
    {
        let contactPicker = CNContactPickerViewController()
        contactPicker.delegate = self
        contactPicker.displayedPropertyKeys =
            [CNContactPhoneNumbersKey]
        self.presentViewController(contactPicker, animated: true, completion: nil)
    }

    func contactPicker(picker: CNContactPickerViewController, didSelectContacts ContctAryVar: [CNContact])
    {
        for ContctVar in ContctAryVar
        {
            let ContctDtlVar = ContctDtlCls()
            ContctDtlVar.ManNamVar = CNContactFormatter.stringFromContact(ContctVar, style: .FullName)!

            for ContctNumVar: CNLabeledValue in ContctVar.phoneNumbers
            {
                var MobNumVar  = ((ContctNumVar.value as! CNPhoneNumber).valueForKey("digits") as? String)!
                if(MobNumVar.Len() > 10)
                {
                    MobNumVar = MobNumVar.GetLstSubSrgFnc(10)
                }
                ContctDtlVar.MobNumVar = MobNumVar
                ContctDtlAryVar.append(ContctDtlVar)
            }
        }

     delegate.didFetchContacts([contact])
    navigationController?.popViewControllerAnimated(true)
    }

Here is a swift 4 version

@IBAction func addPhoneContact(_ sender: UIButton) {
    let contactPicker = CNContactPickerViewController()
    contactPicker.delegate = self
    contactPicker.displayedPropertyKeys =
        [CNContactPhoneNumbersKey]
    self.present(contactPicker, animated: true, completion: nil)
}

extension ViewController: CNContactPickerDelegate {
  func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
      picker.dismiss(animated: true, completion: nil)
      let name = CNContactFormatter.string(from: contact, style: .fullName)
      for number in contact.phoneNumbers {
        let mobile = number.value.value(forKey: "digits") as? String
        if (mobile?.count)! > 7 {
            // your code goes here
        }
     }
  }
}
