How to fetch all contacts from my phonebook iOS swift

Solution:

Before run the below code must add the "Privacy - Contacts Usage Description" key in info.plist

I had created the below class for print the contacts in my phonebook.

import UIKit

import ContactsUI

import Foundation

class ViewController: UIViewController {

    override func viewDidLoad() {

        super.viewDidLoad()

        print("called")

        let contactStore = CNContactStore()

        var contacts = [CNContact]()

        let keys = [CNContactFormatter.descriptorForRequiredKeys(for: .fullName)]

        let request = CNContactFetchRequest(keysToFetch: keys)

        do {

            try contactStore.enumerateContacts(with: request) {

                (contact, stop) in

                // Array containing all unified contacts from everywhere

                contacts.append(contact)

                self.getcontacts()

            }

            print("hai",contacts)

        }

        catch {

            print("unable to fetch contacts")

        }

    }

    

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

        // Dispose of any resources that can be recreated.

    }

    @IBAction func didTapOnNewcontact(_ sender: Any) {

        let con = CNContact()

        let vc = CNContactViewController(forNewContact: con)

       self.navigationController?.pushViewController(vc, animated: true)

    }

    

    func getcontacts() {

        let contactStore = CNContactStore()

        var contacts = [CNContact]()

        let keys = [

            CNContactFormatter.descriptorForRequiredKeys(for: .fullName),

            CNContactPhoneNumbersKey,

            CNContactEmailAddressesKey

            ] as [Any]

        let request = CNContactFetchRequest(keysToFetch: keys as! [CNKeyDescriptor])

        do {

            try contactStore.enumerateContacts(with: request){

                (contact, stop) in

                // Array containing all unified contacts from everywhere

                contacts.append(contact)

                for phoneNumber in contact.phoneNumbers {

                    if let number = phoneNumber.value as? CNPhoneNumber, let label = phoneNumber.label {

                        let localizedLabel = CNLabeledValue<CNPhoneNumber>.localizedString(forLabel: label)

                        print("\(contact.givenName) \(contact.familyName) tel:\(localizedLabel) -- \(number.stringValue), email: \(contact.emailAddresses)")

                    }

                }

            }

            print(contacts)

        } catch {

            print("unable to fetch contacts")

        }

    }

}
