Use MKAnnotation to move on the next View Controller

Question

i'm new in swift programming. I want when user tap a MKAnnotationPoint to move on the next view controller. The way i do it now is by pressing the Button "Button" as you see at the top of image1. My code:

mapViewController.swift

import UIKit
import MapKit
import CoreLocation

class mapViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate, CLLocationManagerDelegate, MKMapViewDelegate {

    // MARK: Properties
    let pin = UIImage(named: "pin")
    var annotationTouched = String()
    var viaSegue = MKAnnotationView()

    // MARK: MAP
    @IBOutlet weak var mapView: MKMapView!


    let coreLocationManager = CLLocationManager()
    let locations = LocationList().Location

    // all locations will be stored on this array
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
    {
        let location = locations [0]

        //map zoomed
        let span:MKCoordinateSpan = MKCoordinateSpanMake(0.003, 0.003)
        //users location
        let myLocation:CLLocationCoordinate2D = CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude)

        let region:MKCoordinateRegion = MKCoordinateRegionMake(myLocation, span)
        mapView.setRegion(region, animated: true)

        self.mapView.showsUserLocation = true
    }

    // func to change red pin to my custom pin
    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView?
    {

        if let annotation = annotation as? Locations{
            if let view = mapView.dequeueReusableAnnotationView(withIdentifier: annotation.identifier){
                return view
            }else{
                let view = MKAnnotationView(annotation: annotation, reuseIdentifier: annotation.identifier)
                view.image = pin
                view.isEnabled = true
                view.canShowCallout = true
                //view.leftCalloutAccessoryView = UIImageView(image: pin)
                let btn = UIButton(type: .detailDisclosure)
                view.rightCalloutAccessoryView = btn

                return view
            }
        }
        return nil
    }

    // assigning the pin that is selected in the map to the annotation touched variable
    func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView)
    {
        if let annotation = view.annotation as? Locations {
            annotationTouched = annotation.title ?? "No title"
        }
    }


    override func viewDidLoad()
    {
        super.viewDidLoad()

        coreLocationManager.delegate = self
        //desired accuracy is the best accuracy, very accurate data for the location
        coreLocationManager.desiredAccuracy = kCLLocationAccuracyBest
        //request authorization from the user when user using my app
        coreLocationManager.requestWhenInUseAuthorization()

        coreLocationManager.startUpdatingLocation()

        mapView.delegate = self

        mapView.addAnnotations(locations)
    }

    // passing the name of the place on the next view controller which is the review view controller (RateViewController)
    override func prepare(for segue: UIStoryboardSegue, sender: Any?)
    {
        let destViewController : RateViewController = segue.destination as! RateViewController
        destViewController.placeLabelString = annotationTouched

    }


}

Locations.swift

import UIKit
import MapKit

class Locations: NSObject, MKAnnotation {
    // required coordinate, title, and the reuse identifier for this annotation
    var identifier = "locations"
    var title: String?
    var coordinate: CLLocationCoordinate2D
    //initializer taking a name, a latitude and longitude to populate the title and coordinate for each instance of this object
    init(name:String,lat:CLLocationDegrees,long:CLLocationDegrees){
        title = name
        coordinate = CLLocationCoordinate2DMake(lat, long)
    }

}
// Creating the list of the places that will be pinned in map
class LocationList: NSObject {
    var Location = [Locations]()
    override init(){
        Location += [Locations(name: "Dio Con Dio", lat: 40.590130, long: 23.036610)]
        Location += [Locations(name: "Paradosiako - Panorama", lat: 40.590102, long:23.036180)]
        Location += [Locations(name: "Veranda",  lat: 40.607740, long: 23.103044)]
        Location += [Locations(name: "Markiz",  lat: 40.634252, long: 22.936276)]
        Location += [Locations(name: "Moi Lounge Bar",  lat: 40.653481, long: 22.994131)]
        Location += [Locations(name: "Boulevard Lounge Bar",  lat: 40.658462, long: 22.983198)]
        Location += [Locations(name: "Ernést Hébrard",  lat: 40.631829, long: 22.941014)]
        Location += [Locations(name: "Tribeca - All Day & Night Bar",  lat: 40.631029, long: 22.942396)]

    }
}

Answer 1

Create a segue from your mapViewController to your destination viewController and then do it like this:

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
    self.performSegue(withIdentifier: "destViewController", sender: nil)
}

Here is a sample project I created that shows you how it works.

To edit the segue identifier do this:
