I would like to create a map with a map pin as Paul Hudson describes in his post How to show annotations in a map View dated Feb 9, 2021. I am passing the coordinates dynamically through a call to MapView using CLLocationCoordinate2D instead of hardcoding the location.

struct DetailView: View {

var coordinate: CLLocationCoordinate2D {
     CLLocationCoordinate2D(
     latitude: item.entryLat,
     longitude: item.entryLong)
     }

     var body: some View {

     MapView(coordinate: coordinate)

In MapView I'm not sure what to do with my coordinates. Store them in the location structure?

struct MapView: View {

    var coordinate: CLLocationCoordinate2D

Here is the sample code from the article:

struct Location: Identifiable {
    let id = UUID()
    let name: String
    let coordinate: CLLocationCoordinate2D
}

 let annotations = [
        Location(name: "London", coordinate: CLLocationCoordinate2D(latitude: 51.507222, longitude: -0.1275)),
        Location(name: "Paris", coordinate: CLLocationCoordinate2D(latitude: 48.8567, longitude: 2.3508)),
        Location(name: "Rome", coordinate: CLLocationCoordinate2D(latitude: 41.9, longitude: 12.5)),
        Location(name: "Washington DC", coordinate: CLLocationCoordinate2D(latitude: 38.895111, longitude: -77.036667))
    ]

struct ContentView: View {
    @State private var region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 51.507222, longitude: -0.1275), span: MKCoordinateSpan(latitudeDelta: 10, longitudeDelta: 10))

    var body: some View {
        Map(coordinateRegion: $region, annotationItems: annotations) {
            MapPin(coordinate: $0.coordinate)
        }
    }
}

@travelBuf No idea if you already solved this issue, I you did I’d like to know how you did it. In my case, I need to read in a lot (300+) locations from a server and display the pointers on the map. I found a work around, it’s probably not the best but it works for now.

In short my solution: Programmatically save the annotations information from the server in a local stored JSON file and use that file to display your annotations on the map. It’s most likely not the best solution but it works for me at the moment. I you require more info let me know, it’s just too much code to post here.
