ios - 在 swiftUI 2 中将 MapMarker 添加到 MapKit

Question

我正在尝试使用新的 Mapkit SwiftUI view我可以显示某个区域的 map ，但我不知道如何显示 Map Marker .
这就是我所拥有的:

import SwiftUI
import MapKit

struct ContentView: View {
    @State private var region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 38.8977, longitude: -77.0365), span: MKCoordinateSpan(latitudeDelta: 0.5, longitudeDelta: 0.5))
    var location1 =  MapMarker(coordinate: CLLocationCoordinate2D(latitude: 38.8977, longitude: -77.0365), tint: .red)
    
    
    var body: some View {
        Map(coordinateRegion: $region, showsUserLocation: true).edgesIgnoringSafeArea(.all)
    }
}

有谁知道怎么加location1到 map ？我找到了 this但我无法让它发挥作用

这是一个简单的演示。使用 Xcode 12/iOS 14 测试

import CoreLocation
import MapKit

struct Marker: Identifiable {
    let id = UUID()
    var location: MapMarker
}

struct DemoView: View {

    @State private var region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 38.8977, longitude: -77.0365), span: MKCoordinateSpan(latitudeDelta: 0.5, longitudeDelta: 0.5))

    let markers = [Marker(location: MapMarker(coordinate: CLLocationCoordinate2D(latitude: 38.8977, longitude: -77.0365), tint: .red))]


    var body: some View {
        Map(coordinateRegion: $region, showsUserLocation: true, 
          annotationItems: markers) { marker in
            marker.location
        }.edgesIgnoringSafeArea(.all)
    }
}
