func mapView(_ mapView: MKMapView, didLongPressAt coordinate: CLLocationCoordinate2D) {
    // Create a custom pin
    let customPin = self.mapView.addCustomAnnotation(coordinate: coordinate, title: "New Marker", subtitle: "This is a new marker")
    // Show an alert for adding a new pin
    let alert = UIAlertController(title: "New Pin", message: "This is a new pin", preferredStyle: .alert)
    alert.addAction(UIAlertAction(title: "X", style: .destructive, handler: { action in
        self.mapView.removeAnnotation(customPin)
