Add the camera on current position of the user on the map - ios

Question

I added this code in my viewController
import UIKit
import CoreLocation
import GoogleMaps
class CourseClass2: UIViewController, UITableViewDelegate, UITableViewDataSource, UINavigationControllerDelegate {
#IBOutlet weak var mapView: GMSMapView!
}
and this extension
extension CourseClass2: CLLocationManagerDelegate {
func determineMyCurrentLocation() {
guard currentLocation == nil else {
return
}
locationManager = CLLocationManager()
locationManager?.delegate = self
locationManager?.desiredAccuracy = kCLLocationAccuracyBest
locationManager?.requestWhenInUseAuthorization()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation:CLLocation = locations[0] as CLLocation
manager.stopUpdatingLocation()
print("user latitude = \(userLocation.coordinate.latitude)")
print("user longitude = \(userLocation.coordinate.longitude)")
didReceiveUserLocation(userLocation)
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("Error \(error)")
errorGettingCurrentLocation(error.localizedDescription)
}
public func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
if status == .authorizedWhenInUse || status == .authorizedAlways {
locationManager?.startUpdatingLocation()
//locationManager.startUpdatingHeading()
} else if status == .denied || status == .restricted {
errorGettingCurrentLocation("Location access denied")
}
}
func errorGettingCurrentLocation(_ errorMessage:String) {
let alert = UIAlertController.init(title: "Error", message: errorMessage, preferredStyle: .alert)
alert.addAction(UIAlertAction.init(title: "Cancel", style: .cancel, handler: nil))
present(alert, animated: true, completion: nil)
}
}
to get the user location. Now i would like to add in the viewDidLoad of my controller a camera like let camera = GMSCameraPosition.camera(withLatitude: , longitude: , zoom: 14) on the user position, but how can i do to use in this line the latitude and longitude of my user current position that i found with my extension?

You need to call locationManager.startUpdatingLocation() in viewDidLoad() where locationManager is CLLocationManager object. As soon as your current location is retrieved, didUpdateLocations delegate method is called where you can set the camera position as follows:
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation = locations.last
let location = GMSCameraPosition.camera(withLatitude: userLocation!.coordinate.latitude, longitude: userLocation!.coordinate.longitude, zoom: 16.0)
mapView.animate(to: location)
}
