Center Map on iOS in Swift

Hi, I'm doing a tourism application in which there are several cabins, places to eat and visit in this case, each one has a button that goes to a single map in which there are markers to show the location, and I need the center of the map load depending on the button that was pressed. I add the code of the mapController.

import UIKit
import MapKit

class mapController: UIViewController {


    @IBOutlet weak var myMapView: MKMapView!


    override func viewDidLoad() {
        super.viewDidLoad()
        mapTajMahal()

    }

    func mapTajMahal()
    {
        //Taj Mahal Coordinates: 27.175015, 78.042139

        // Coordinates
        let tajLat:CLLocationDegrees = -39.849254
        let tajLong:CLLocationDegrees = -71.994215

        let tajCoordinate = CLLocationCoordinate2D(latitude: tajLat, longitude: tajLong)

        let mocho = CLLocationCoordinate2D(latitude: -39.849152, longitude: -71.943082)
        let aitue = CLLocationCoordinate2D(latitude: -39.849581, longitude: -71.945078)
        let rucapillan = CLLocationCoordinate2D(latitude: -39.833403841808995, longitude:-72.07239013854979)
        let c_elportal = CLLocationCoordinate2D(latitude: -39.848834,longitude: -71.937480)

        let latDelta:CLLocationDegrees = 0.2
        let longDelta:CLLocationDegrees = 0.2
        let tajSpan = MKCoordinateSpan(latitudeDelta: latDelta, longitudeDelta: longDelta)
