Transfer of Description and Image using Segue - ios

Question

I am currently trying to create a map app that has around 20 pins. I have made a segue so that the Pin's Annotation's Title is transferred. However now I need to implement it so that a description is correctly selected from a series of 20 .txt file descriptions and 20 images. But I believe I am able to do it with one Segue.
Here is my current code
import UIKit
import MapKit
import CoreLocation
class ViewController: UIViewController, MKMapViewDelegate,CLLocationManagerDelegate {
#IBOutlet weak var MapView: MKMapView!
let manager = CLLocationManager()
var artworkPin:Artwork!
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
//let location = locations[0]
//let span:MKCoordinateSpan = MKCoordinateSpanMake(0.02, 0.02)
//let myLocation:CLLocationCoordinate2D = CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude)
}
override func viewDidLoad() {
super.viewDidLoad()
// tracking user's location
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.requestWhenInUseAuthorization()
manager.startUpdatingLocation()
// Setting up Map
let distanceSpan:CLLocationDegrees = 2000
MapView.setRegion(MKCoordinateRegionMakeWithDistance(CLLocationCoordinate2DMake(-39.0556253, 174.0752278), distanceSpan, distanceSpan), animated: true)
MapView.showsUserLocation = true
MapView.delegate = self
// artwork on map
let windwandcoord: CLLocationCoordinate2D = CLLocationCoordinate2DMake(-39.055961,174.072288)
artworkPin = Artwork(title:"Wind Wand",locationName:"Majestic",discipline:"Statue",
coordinate:windwandcoord)
MapView.addAnnotation(artworkPin)
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView?
{
if annotation is MKUserLocation {return nil}
let reuseId = "pin"
var pinView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId) as? MKPinAnnotationView
if pinView == nil {
pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
pinView!.canShowCallout = true
pinView!.animatesDrop = true
pinView!.calloutOffset = CGPoint(x: -5, y: 5)
let calloutButton = UIButton(type: .detailDisclosure)
pinView!.rightCalloutAccessoryView = calloutButton
pinView!.sizeToFit()
}
else {
pinView!.annotation = annotation
}
return pinView
}
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
if control == view.rightCalloutAccessoryView {
performSegue(withIdentifier: "no", sender:self)
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let ViewTwo = segue.destination as! ViewTwo
ViewTwo.artworkPin = self.artworkPin
}
}
I also don't think this will give the correct title if I add another pin am I correct? Because it will simply take the name of artworkPin rather than of any variable pin added.
Thanks for any help.
