2. Check Certificate, Identifiers, and Profiles in Developer Account
3. import UserNotifications in AppDelegate
4. Add registerForPushNotifications() method in AppDelegate before close bracket

	UNUserNotificationCenter.current() // 1
	.requestAuthorization(options: [.alert, .sound, .badge]) { // 2
		granted, error in
		print("Permission granted: \\(granted)") // 3
	}
}

func getNotificationSettings() {
	UNUserNotificationCenter.current().getNotificationSettings { settings in
		print("Notification settings: \\(settings)")
	}

UNUserNotificationCenter.current()
.requestAuthorization(options: [.alert, .sound, .badge]) {
	[weak self] granted, error in
	print("Permission granted: \\(granted)")
	guard granted else { return }
	self?.getNotificationSettings()
}

guard settings.authorizationStatus == .authorized else { return }

DispatchQueue.main.async {

UIApplication.shared.registerForRemoteNotifications()
