Add single pin to Mapkit with SwiftUI - ios

Question

How can I add a simple pin on my map with Xcode 11 GM / SwiftUI.
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.
import SwiftUI
import MapKit
struct ContentView: UIViewRepresentable {
func makeUIView(context: Context) -> 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()
}
}
I would appreciate any suggestions, thanks.

Update your code:
struct ContentView: UIViewRepresentable {
func makeUIView(context: Context) -> MKMapView {
MKMapView(frame: .zero)
}
func updateUIView(_ view: MKMapView, context: Context) {
// 1
view.mapType = MKMapType.standard // (satellite)
// 2
let mylocation = CLLocationCoordinate2D(latitude: -6.863190,longitude: -79.818250)
// 3
let coordinate = CLLocationCoordinate2D(
latitude: -6.864138, longitude: -79.819634)
let span = MKCoordinateSpan(latitudeDelta: 0.005, longitudeDelta: 0.005)
let region = MKCoordinateRegion(center: coordinate, span: span)
view.setRegion(region, animated: true)
// 4
let annotation = MKPointAnnotation()
annotation.coordinate = mylocation
annotation.title = "My Location"
annotation.subtitle = "Visit us soon"
view.addAnnotation(annotation)
}
}

Found this post looking for how to add a simple pin/marker to XCode's MapKit and SwiftUI tutorials. Sharing a workable answer for using the new Map SwiftUI View rather than the more complex MKMapView in OP's question.
import SwiftUI
import MapKit
struct Marker: Identifiable {
let id = UUID()
var location: MapMarker
}
struct MapView: View {
var coordinate: CLLocationCoordinate2D
#State private var region = MKCoordinateRegion()
#State var markers = [Marker(location: MapMarker(coordinate: CLLocationCoordinate2D(latitude: -25.342863, longitude: 131.036974), tint: .blue))]
var body: some View {
Map(coordinateRegion: $region, annotationItems: markers) { marker in
marker.location }
.onAppear {
setRegion(coordinate)
}
}
private func setRegion(_ coordinate: CLLocationCoordinate2D) {
region = MKCoordinateRegion(
center: coordinate,
span: MKCoordinateSpan(latitudeDelta: 0.2, longitudeDelta: 0.2)
)
markers = [Marker(location: MapMarker(coordinate: coordinate, tint: .blue))]
}
}
struct MapView_Previews: PreviewProvider {
static var previews: some View {
MapView(coordinate: CLLocationCoordinate2D(latitude: -25.342863, longitude: 131.036974))
}
}
