The centre locations in MapKit is not visible in the UiLabel - swift

Question

Unable to show the centrelocation of map in the label!
import UIKit
import MapKit
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate {
#IBOutlet weak var myMapView: MKMapView!
#IBOutlet weak var addressLabel: UILabel!
let locationManager = CLLocationManager()
let regionInMeters: Double = 10000
var previousLocation: CLLocation?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
checkLocationServices()
}
func setupLocationManager() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
}
func centerViewOnUserLocation() {
if let location = locationManager.location?.coordinate {
let region = MKCoordinateRegion.init(center: location, latitudinalMeters: regionInMeters, longitudinalMeters: regionInMeters)
myMapView.setRegion(region, animated: true)
}
}
// the Location service
func checkLocationServices() {
if CLLocationManager.locationServicesEnabled() {
setupLocationManager()
checkLocationAuthorisation()
} else {
//show user to turn ON the services
}
}
func checkLocationAuthorisation() {
switch CLLocationManager.authorizationStatus() {
case .authorizedWhenInUse:
// do the stuff
startTrackingLocation()
case .denied:
//Alert to turn ON the permissions
break
case .notDetermined:
locationManager.requestWhenInUseAuthorization()
case .restricted:
// Alert to show what's up
break
case .authorizedAlways:
break
}
}
func startTrackingLocation() {
myMapView.showsUserLocation = true
centerViewOnUserLocation()
locationManager.startUpdatingLocation()
previousLocation = getCenterLocation(for: myMapView)
}
func getCenterLocation(for mapView: MKMapView) -> CLLocation {
let latitude = mapView.centerCoordinate.latitude
let longitude = mapView.centerCoordinate.longitude
return CLLocation(latitude: latitude, longitude: longitude)
}
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
// We'll be back
checkLocationAuthorisation()
}
func mapView(_ mapView: MKMapView, regionDidChangeAnimated animated: Bool) {
let center = getCenterLocation(for: myMapView)
let geoCoder = CLGeocoder()
guard let previousLocation = self.previousLocation else { return }
guard center.distance(from: previousLocation) > 50 else { return }
self.previousLocation = center
geoCoder.reverseGeocodeLocation(center) { [weak self] (placemarks, error) in
guard let self = self else { return }
if let _ = error {
//TODO: Show alert informing the user
return
}
guard let placemark = placemarks?.first else {
//TODO: Show alert informing the user
return
}
let streetNumber = placemark.subThoroughfare ?? ""
let streetName = placemark.subThoroughfare ?? ""
DispatchQueue.main.async {
self.addressLabel.text = "\(streetNumber) \(streetName)"
}
}
}
#IBAction func satelliteView(_ sender: Any) {
myMapView.mapType = MKMapType.satellite
}
#IBAction func hybridView(_ sender: Any) {
myMapView.mapType = MKMapType.hybrid
}
#IBAction func standardView(_ sender: Any) {
myMapView.mapType = MKMapType.standard
}
#IBAction func findDirections(_ sender: Any) {
}
}
The label in the app is supposed to show the centrelocation(pin) of the map. But don't know for where is it going wrong!

Changed the getCenterlocation function and its working fine!
`func getCenterLocation(for mapView: MKMapView) -> CLLocation {
let latitude=mapView.centerCoordinate.latitude
let longitude=mapView.centerCoordinate.longitude
return CLLocation(latitude:latitude, longitude:longitude)
}
func getCenterLocation(for myMapView: MKMapView) -> CLLocation {
let latitude=myMapView.centerCoordinate.latitude
let longitude=myMapView.centerCoordinate.longitude
return CLLocation(latitude:latitude, longitude:longitude)
}`
