How do you get a label to be read as a number?

My map annotation works well when physically putting the numbers in, but, how do I use it so, for example, latitudelabel.text is read as the latitude rather than 38.897957? Here is the code:

func showEmergenyOnMap() {      let emergency = MKPointAnnotation()     emergency.title = "Ongoing Emergency"     emergency.coordinate = CLLocationCoordinate2D(latitude: 38.897957, longitude: -77.036560)     Map.addAnnotation(emergency)  }
