This tutorial shows how to show a Map.

This tutorial shows how to show a Map with Current Location on it.
SwiftUI doesn't support Map View so we have to use MapKit and wrap it inside UIViewRepresentable.
ContentView.swift
import SwiftUI
import UIKit
import MapKit
struct ContentView: View {
var body: some View {
MapView()
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
struct MapView: UIViewRepresentable {
var locationManager = CLLocationManager()
func setupManager() {
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.requestAlwaysAuthorization()
}
func makeUIView(context: Context) -> MKMapView {
setupManager()
let mapView = MKMapView(frame: UIScreen.main.bounds)
mapView.showsUserLocation = true
mapView.userTrackingMode = .follow
return mapView
}
func updateUIView(_ uiView: MKMapView, context: Context) {
}
}
Simulator (current location is not visible on simulator)
