How to determine if device location permission is denied twice in iOS swift?

If Location Service is disabled in iPhone(Settings -> Privacy -> Location Services) and when requested for location permission using self.locationManager.requestWhenInUseAuthorization() then app shows system dialog with settings and cancel button.

enter image description here

On click of settings button it redirects Device's location service page.

enter image description here

If Cancel is tapped alert dismisses. And if second time I ask for permission and tap cancel, alert dismisses. And then again if I request third time for location permission then that above system dialog won't be shown.

I have tried CLLocationManager.locationServicesEnabled() which gives me Device location is enabled or disabled. In case of disable state I have written self.locationManager.requestWhenInUseAuthorization() which shows system dialog twice only. Now how shall I determine that system dialog has been denied twice? So that I can show my custom dialog.

if I understand well (your question is a little bit confused) you can do it with UserDefaults like that, I use alert but you can use your code in if statement:

import CoreLocation, set func and UserDefaults:

import UIKit
import CoreLocation

class Prova: UIViewController {

let locationManager = CLLocationManager() // location manager

override func viewDidLoad() {
    super.viewDidLoad()

    view.backgroundColor = .white
    locationManagerDidChangeAuthorization(locationManager)
}

var control = 0 // set var to control user tap denied
func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {
    switch manager.authorizationStatus {
    case .authorizedAlways , .authorizedWhenInUse:
        print("authorized always and when in use")
        break
    case .notDetermined , .denied , .restricted:
        
        print("authorized denied or restricted")
        let res = UserDefaults.standard.integer(forKey: "ok")
        control = res
        UserDefaults.standard.set(res, forKey: "ok")
        
        if res >= 1 { // first = 0 second = 1 - Two times
            DispatchQueue.main.async {
                let myAlert = UIAlertController(title: "Ooooooop!", message: "you're denied or restricted for two times", preferredStyle: .alert)
                myAlert.addAction(UIAlertAction(title: "Cancel", style: .destructive))
                UserDefaults.standard.set(self.control + 1, forKey: "ok")
                self.present(myAlert, animated: true)
            }
        } else {
            DispatchQueue.main.async {
                let myAlert = UIAlertController(title: "OK", message: "you're denied for: \(self.control + 1) times", preferredStyle: .alert)
                myAlert.addAction(UIAlertAction(title: "Cancel", style: .destructive))
                UserDefaults.standard.set(self.control + 1, forKey: "ok")
                self.present(myAlert, animated: true)
            }
        }
        break
    default:
        break
    }
    print(" time denied:",control)
 }
}
