title: Add single pin to Mapkit with SwiftUI
body: <p>How can I add a simple pin on my map with Xcode 11 GM / SwiftUI.</p>
  
  <p>My code is as follows (here it shows me the map centered with the coordinates) but I want to show there only one pin of other coordinates.</p>
  
  <pre><code>import SwiftUI
  import MapKit
  
  struct ContentView: UIViewRepresentable {
      func makeUIView(context: Context) -&gt; MKMapView {
          MKMapView(frame: .zero)
      }
  
      func updateUIView(_ view: MKMapView, context: Context) {
          let coordinate = CLLocationCoordinate2D(
              latitude: 34.011_286, longitude: -116.166_868)
          let span = MKCoordinateSpan(latitudeDelta: 2.0, longitudeDelta: 2.0)
          let region = MKCoordinateRegion(center: coordinate, span: span)
          view.setRegion(region, animated: true)
  
  
  
      }
  }
  
  struct ContentView_Previews: PreviewProvider {
      static var previews: some View {
          ContentView()
      }
  }
  </code></pre>
  
  <p>I would appreciate any suggestions, thanks.</p>
