CoreLocation returns .notDetermined on Simulator even though Location Services are enabled, how can I manually trigger the authorization dialog?

In my Info.plist, I have added the necessary keys for location permissions.

• can you show what your appStateManager is, and how you pass it to the view – workingdog support Ukraine Commented Feb 21 at 6:57
• Thanks for your response! I've added the relevant details about appStateManager and how it's passed to the view. – Ehz uiq Commented Feb 21 at 8:03
• I recommend doing authorization and location updates from separate View structs, thus 2 managers and 2 delegate objects. – malhal Commented Feb 21 at 12:18
• AFAIK, you don't have to do anything special to ask for permissions, they will appear by themself when you launch the App. – workingdog support Ukraine Commented Feb 22 at 8:14

You have to request when in use before always

func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {
  switch manager.authorizationStatus {
  case .authorizedWhenInUse:
     authorizationStatus = .authorizedWhenInUse
              manager.requestAlwaysAuthorization()
     locationManager.requestLocation()
     break
     
  case .restricted:
     authorizationStatus = .restricted
     break
     
  case .denied:
     authorizationStatus = .denied
     break
     
  case .notDetermined:
     print("location Manager: notDetermined")
     authorizationStatus = .notDetermined
              manager.requestWhenInUseAuthorization()
     break
     
  default:
     break
  }
  
  print("location Manager: \(locationManager.authorizationStatus)")

}

Also init is too early so request authorization it us better to use onAppear or task, sometimes you need to add a small delay.

                  manager.requestWhenInUseAuthorization()
