Mapbox - calloutAccessoryControllerTapped - swift

Question

I am having an issue with my calloutAccessoryControllerTapped. At the minute I have two buttons within my callout - each which will segue to a modal pop up on my map view. At the minute my segue works but both buttons segue to the same popup. I need to be able to differentiate between buttons and their segue.
Is this possible? I have googled this question and many answers seem to suggest using this line of code below
if (control == view.leftCalloutAccessoryView) {
However, this is coming up with an error "Value of type 'UIView' has no member 'leftCalloutAccessoryView'. I would really appreciate if somebody could help me with this issue and apologise if I have not clearly explained the issue, I have done so to my best extent.
Below is my code:
func mapView(_ mapView: MGLMapView, annotationCanShowCallout annotation: MGLAnnotation) -> Bool {
return true
}
func mapView(_ mapView: MGLMapView, annotation: MGLAnnotation, calloutAccessoryControlTapped control: UIControl) {
self.performSegue(withIdentifier: "Show", sender: view)
}
func mapView(_ mapView: MGLMapView, rightCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? {
guard let skateAnnotation = annotation as? SkateAnnotation else { return nil }
if skateAnnotation.canEdit {
return UIButton(type: .detailDisclosure)
}
return nil
}
func mapView(_ mapView: MGLMapView, leftCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? {
return UIButton(type: .contactAdd)
}
func mapView(_ mapView: MGLMapView, imageFor annotation: MGLAnnotation) -> MGLAnnotationImage? {
return nil
}
}

Something simple (change code for your own requirements as necessary) like this works to distinguish between the left and right callout accessory controls.
func mapView(_ mapView: MGLMapView, leftCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? {
let button = UIButton(type: .detailDisclosure)
button.tag = 100
return button
}
func mapView(_ mapView: MGLMapView, rightCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? {
let button = UIButton(type: .detailDisclosure)
button.tag = 101
return button
}
func mapView(_ mapView: MGLMapView, annotation: MGLAnnotation, calloutAccessoryControlTapped control: UIControl) {
// Hide the callout view.
mapView.deselectAnnotation(annotation, animated: false)
if control.tag == 100 {
print("left")
} else if control.tag == 101 {
print("right")
}
}
