Xcode – How to fix Thread 1: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value?

I have a problem with the Users Location.

When im trying to build the program it gets this error code: (Thread 1: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value)

My code:

import UIKit
import MapKit
   


class ViewController: UIViewController {
    
    private let locationManager = CLLocationManager()
    private var currentCoordinate: CLLocationCoordinate2D?
    
    @IBOutlet weak var mapView: MKMapView!
    override func viewDidLoad() {
        super.viewDidLoad()
        configerLocationServices()
    }
    
    private func configerLocationServices() {
        locationManager.delegate = self
        
        let status = CLLocationManager.authorizationStatus()
        
        if status == .notDetermined {
            locationManager.requestWhenInUseAuthorization()
        } else if status == .authorizedAlways || status == .authorizedWhenInUse {
            beginLocationUpdates(locationManager: locationManager)
        }
    }
    
    private func beginLocationUpdates(locationManager: CLLocationManager) {
        mapView.showsUserLocation = true //<--- the problem is here
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.startUpdatingLocation()
    }
    
    private func zoomToLastestLocation(with coordinate: CLLocationCoordinate2D) {
        let zoomRegion = MKCoordinateRegion(center: coordinate, latitudinalMeters: 10000, longitudinalMeters: 10000)
        mapView.setRegion(zoomRegion, animated: true)
    }
}

extension ViewController: CLLocationManagerDelegate {
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        print("Did get latest Location")
        
        guard let latestLocation = locations.first else { return }
        
        if currentCoordinate == nil {
            zoomToLastestLocation(with: latestLocation.coordinate)
        }
            
        currentCoordinate = latestLocation.coordinate
        
    }
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        print("The Status changed")
        if status == .authorizedAlways || status == .authorizedWhenInUse {
            self.beginLocationUpdates(locationManager: manager)
        }
    }
}

I don’t know what im doing wrong, has anyone the solution?

Thank you in advance.
