Need help making a MKPointAnnotation a button - swift

Question

i am not sure how to make the MKPointAnnotations a button i want to be able to click on the pop up to send me to another screen
import UIKit
import MapKit
import Firebase
//building the pin ticker
class mapViewController: UIViewController, MKMapViewDelegate{
//class so an image can be added to point annotation
/* class CustomPointAnnotation: MKPointAnnotation{
var imageName: String!
}*/
#IBOutlet weak var map: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
//set the map location to a specific location when the view loads
let centerLocation = CLLocationCoordinate2DMake(39.863048 , -75.357583)
//logingitude and latitude that the map will cover
let mapSpan = MKCoordinateSpan(latitudeDelta: 0.001, longitudeDelta: 0.001)
//range that the map will show
let mapRange = MKCoordinateRegion(center: centerLocation, span: mapSpan)
//what we will see on the map
self.map.setRegion(mapRange, animated: false)
addAnnotation()
map.delegate = self
let rotate = CGFloat(180)
let regionradius : CLLocationDistance=300.0
let region = MKCoordinateRegion(center: centerLocation, latitudinalMeters: regionradius, longitudinalMeters: regionradius)
//rotation that shows the map is aligned
map.camera.pitch = rotate;
map.setRegion(region, animated: true)
map.delegate = self
map.isUserInteractionEnabled = true
//allows user to still interact with the items on map
let pitch: CGFloat = 300
let heading = 335.0
var camera: MKMapCamera?
camera = MKMapCamera(lookingAtCenter: centerLocation, fromDistance: regionradius, pitch: pitch, heading: heading)
map.camera = camera!
//disables clickables on map
map.isRotateEnabled = false;
map.isZoomEnabled = false;
map.isScrollEnabled = false;
map.showsCompass = false;
}
//funtion to create annotations
private func addAnnotation(){
let parkSpaceOne = MKPointAnnotation()
let parkSpaceTwo = MKPointAnnotation()
let db = Firestore.firestore()
//grabs all the coordinates of the parking spaces in firebase
db.collection("ParkingSpaces").getDocuments() { (querySnapshot, err) in
if let err = err {
print("Error getting documents: \(err)")
} else {
for document in querySnapshot!.documents {
if let coords = document.get("coordinate") {
let point = coords as! GeoPoint
let lat = point.latitude
let lon = point.longitude
//string variable for spot field in firebase
let spotpone = document.get("spot") as! String
let spotptwo = document.get("spot") as! String
//if the spot in firbase matches the string then take the coordinates, add them to an annotation and place on the map
if (spotpone == "p1"){
parkSpaceOne.title = "P1"
parkSpaceOne.coordinate = CLLocationCoordinate2D(latitude: lat, longitude: lon)
self.map.addAnnotation(parkSpaceOne)
}
else if (spotptwo == "p2"){
parkSpaceTwo.title = "P2"
parkSpaceTwo.coordinate = CLLocationCoordinate2D(latitude: lat, longitude: lon)
self.map.addAnnotation(parkSpaceTwo)
}
}
}
}
}
//
}
}

Take a look at the docs
You can detect when the user selects an annotation:
func mapView(MKMapView, didSelect: MKAnnotationView)
Tells the delegate that one of its annotation views was selected.
As well as
func mapView(MKMapView, annotationView: MKAnnotationView, calloutAccessoryControlTapped: UIControl)
Tells the delegate that the user tapped one of the annotation view’s
accessory buttons.
