Answer 1

import ContactsUI
and include - CNContactPickerDelegate

import ContactsUI

class YourViewController: CNContactPickerDelegate{

    //MARK:- contact picker
    func onClickPickContact(){


        let contactPicker = CNContactPickerViewController()
        contactPicker.delegate = self
        contactPicker.displayedPropertyKeys =
            [CNContactGivenNameKey
                , CNContactPhoneNumbersKey]
        self.present(contactPicker, animated: true, completion: nil)

    }

    func contactPicker(_ picker: CNContactPickerViewController,
                       didSelect contactProperty: CNContactProperty) {

    }

    func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
        // You can fetch selected name and number in the following way

        // user name
        let userName:String = contact.givenName

        // user phone number
        let userPhoneNumbers:[CNLabeledValue<CNPhoneNumber>] = contact.phoneNumbers
        let firstPhoneNumber:CNPhoneNumber = userPhoneNumbers[0].value


        // user phone number string
        let primaryPhoneNumberStr:String = firstPhoneNumber.stringValue

        print(primaryPhoneNumberStr)

    }

    func contactPickerDidCancel(_ picker: CNContactPickerViewController) {

    }
}

Answer 2

import ContactsUI

private let contactPicker = CNContactPickerViewController()

Button click that initiates contact picker:

@IBAction func accessContacts(_ sender: Any) {
    contactPicker.delegate = self
    self.present(contactPicker, animated: true, completion: nil)
}

Implement delegate methods

extension YourViewController: CNContactPickerDelegate {

    func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
        let phoneNumberCount = contact.phoneNumbers.count

        guard phoneNumberCount > 0 else {
            dismiss(animated: true)
            //show pop up: "Selected contact does not have a number"
            return
        }

        if phoneNumberCount == 1 {
            setNumberFromContact(contactNumber: contact.phoneNumbers[0].value.stringValue)

        } else {
            let alertController = UIAlertController(title: "Select one of the numbers", message: nil, preferredStyle: .alert)

            for i in 0...phoneNumberCount-1 {
                let phoneAction = UIAlertAction(title: contact.phoneNumbers[i].value.stringValue, style: .default, handler: {
                alert -> Void in
                    self.setNumberFromContact(contactNumber: contact.phoneNumbers[i].value.stringValue)
                })
                alertController.addAction(phoneAction)
            }
            let cancelAction = UIAlertAction(title: "Cancel", style: .destructive, handler: {
            alert -> Void in

            })
            alertController.addAction(cancelAction)

            dismiss(animated: true)
            self.present(alertController, animated: true, completion: nil)
        }
    }

    func setNumberFromContact(contactNumber: String) {

        //UPDATE YOUR NUMBER SELECTION LOGIC AND PERFORM ACTION WITH THE SELECTED NUMBER

        var contactNumber = contactNumber.replacingOccurrences(of: "-", with: "")
        contactNumber = contactNumber.replacingOccurrences(of: "(", with: "")
        contactNumber = contactNumber.replacingOccurrences(of: ")", with: "")
        contactNumber = contactNumber.removeWhitespacesInBetween()
        guard contactNumber.count >= 10 else {
            dismiss(animated: true) {
                self.popUpMessageError(value: 10, message: "Selected contact does not have a valid number")
            }
            return
        }
        textFieldNumber.text = String(contactNumber.suffix(10))

    }

    func contactPickerDidCancel(_ picker: CNContactPickerViewController) {

    }
}

Answer 3

You can use this extension to get a contact name.

extension CNContact {
    open func displayName() -> String {
        return givenName + " " + familyName
    }
}

This is Class to get Some details EPContact

Swift 5 & Contact Picker Get Email

I wanted to show an example of how you can do the same thing you asked for but for email instead and updated for Swift 5 since some of the answers do not compile correctly above. This also has the added bonus of the 'all' option which will concatenate multiple emails into one string if the user selects it or not.

First make sure to import import ContactsUI

Then make sure you have an outlet to your textfield.

@IBOutlet var emailTextField: UITextField!

Next you need to set the contact picker as a member variable of your viewController. This will hold the information for showing the contact picker later.

class EmailViewController: UIViewController {
    @IBOutlet var emailTextField: UITextField!
    private let contactPicker = CNContactPickerViewController()

    //... rest of view controller code, etc...
}

Finally you can simply add this extension to the EmailViewController with the code below:

extension EmailViewController: CNContactPickerDelegate {

    func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
        let emailNumberCount = contact.emailAddresses.count

        //@JA - They have to have at least 1 email address
        guard emailNumberCount > 0 else {
            dismiss(animated: true)
            //show pop up: "Selected contact does not have a number"
            let alertController = UIAlertController(title: "No emails found for contact: "+contact.givenName+" "+contact.familyName, message: nil, preferredStyle: .alert)
            let cancelAction = UIAlertAction(title: "Ok", style: .default, handler: {
            alert -> Void in

            })
            alertController.addAction(cancelAction)
            self.present(alertController, animated: true, completion: nil)
            return
        }

        //@JA - If they have only 1 email it's easy.  If there is many emails we want to concatenate them and separate by commas , , ...
        if emailNumberCount == 1 {
            setEmailFromContact(contactEmail: contact.emailAddresses[0].value as String)
        } else {
            let alertController = UIAlertController(title: "Select an email from contact: "+contact.givenName+" "+contact.familyName+" or select 'All' to send to every email listed.", message: nil, preferredStyle: .alert)

            for i in 0...emailNumberCount-1 {
                let emailAction = UIAlertAction(title: contact.emailAddresses[i].value as String, style: .default, handler: {
                alert -> Void in
                    self.setEmailFromContact(contactEmail: contact.emailAddresses[i].value as String)
                })
                alertController.addAction(emailAction)
            }

            let allAction = UIAlertAction(title: "All", style: .destructive, handler: {
            alert -> Void in
                var emailConcat = ""
                for i in 0...emailNumberCount-1{
                    if(i != emailNumberCount-1){ //@JA - Only add the , if we are not on the last item of the array
                        emailConcat = emailConcat + (contact.emailAddresses[i].value as String)+","
                    }else{
                        emailConcat = emailConcat + (contact.emailAddresses[i].value as String)
                    }
                }
                self.setEmailFromContact(contactEmail: emailConcat)//@JA - Sends the concatenated version of the emails separated by commas
            })
            alertController.addAction(allAction)

            let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: {
            alert -> Void in

            })
            alertController.addAction(cancelAction)

            dismiss(animated: true)
            self.present(alertController, animated: true, completion: nil)
        }
    }

    func setEmailFromContact(contactEmail: String){
        emailTextField.text = contactEmail
    }

    func contactPickerDidCancel(_ picker: CNContactPickerViewController) {
        print("contact picker canceled")
    }
}

To call up the picker in the action event of a button for example you could do this:

@IBAction func contactsButtonPressed(_ sender: UIButton) {
     contactPicker.delegate = self
     self.present(contactPicker, animated: true, completion: nil)
}

contactPicker.delegate = self works because of the extension on the viewController class (emailViewController) in my case that gives it access to the CNContactPickerDelegate protocol functions it requires.

Answer 5

• If contact have more than one phone numbers, then you can get the selected number by comparing the 'contactProperty.identifier' as below -

   public func contactPicker(_ picker: CNContactPickerViewController, didSelect contactProperty: CNContactProperty) { tvName.text = contactProperty.contact.givenName var selectedNo = "" if contactProperty.key == "phoneNumbers" { contactProperty.contact.phoneNumbers.forEach({ phone in if phone.identifier == contactProperty.identifier { selectedNo = phone.value.stringValue } }) } tvContact.text = selectedNo }
