How to access user coordinates - swift

Question

I am trying to access the users coordinates using:
import MapKit
import CoreLocation
override func viewDidLoad() {
super.viewDidLoad()
let locationManager = CLLocationManager()
let userCoordinates = (locationManager.location?.coordinate)!
}
However, it crashes upon the simulator loading. I set the simulator location to Apple, and input privacy keys into info.plist, but I am not sure why this is not grabbing the user location.

There are a few things you need to do first before you can start using a device's current geolocation safely and based on the code you provided I'm going to assume that you might be missing some so here is a common set up using a Google Map, which acts like any other basically:
class YourViewController: UIViewController, CLLocationManagerDelegate {
// properties
var locationManager = CLLocationManager()
var currentCoordinate: CLLocationCoordinate2D?
// load view
override func loadView() {
addLocationManager()
}
// add location manager
func addLocationManager() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.distanceFilter = kCLDistanceFilterNone
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
}
// location manager delegate: did change authorization
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
switch status {
case .restricted:
print("LOCATION ACCESS RESTRICTED")
case .denied:
print("LOCATION ACCESS DENIED")
case .notDetermined:
print("LOCATION ACCESS NOT DETERMINED")
case .authorizedAlways:
fallthrough
case .authorizedWhenInUse:
print("LOCATION STATUS GRANTED")
}
}
// location manager delegate: did fail with error
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
locationManager.stopUpdatingLocation()
print("LOCATION ACCESS ERROR: \(error)")
}
// location manager delegate: did update locations
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let lastLocation = locations.last!
// unhide map when current location is available
if mapView.isHidden {
mapView.camera = GMSCameraPosition.camera(withLatitude: lastLocation.coordinate.latitude, longitude: lastLocation.coordinate.longitude, zoom: 18, bearing: 0, viewingAngle: 0)
mapView.isHidden = false
}
// update current location properties
currentCoordinate = lastLocation.coordinate
}
}
And no need to import CoreLocation if you've imported MapKit.
