This code below pulls up the map view in my iOS app. I want to show the users location with a blue dot like in google maps.
What code do I insert and where to make this happen?

Note: I am looking through the MapKit documentation section of the Apple Developer Documentation website. There is a section called "Displaying the User's Location". I just can't seem to figure out how to integrate the given codes into my code. Such as

Code Block var showsUserLocation: Bool { get set }

etc.
Also note, the code I'm using is from an apple developer tutorial https://developer.apple.com/tutorials/swiftui/creating-and-combining-views
section 5 step 4.

Code Block import SwiftUI
import MapKit
import UIKit
import CoreLocation
struct MapView: UIViewRepresentable {
    var coordinate: CLLocationCoordinate2D
    func makeUIView(context: Context) -> MKMapView {
        MKMapView(frame: .zero)
    }
    func updateUIView(_ uiView: MKMapView, context: Context) {
        let span = MKCoordinateSpan(latitudeDelta: 50, longitudeDelta: 50)
        let region = MKCoordinateRegion(center: coordinate, span: span)
        uiView.setRegion(region, animated: true)
        uiView.mapType = .hybridFlyover
    }
}
struct MapView_Previews: PreviewProvider {
    static var previews: some View {
        MapView(coordinate: landmarkData[0].locationCoordinate)
    }
}

The showsUserLocation property is what you need. What you're probably missing is that location requires you to request permission from the user first. To do that, you need to use a CLLocationManager to request the right type of location permission for your needs, and include the usage description string for that need in the app's Info.plist file.
