如何使用 SwiftUI 在 GoogleMaps 中创建多个标记？

Question

我需要在我的 MapView 中添加多个标记。如何使用swiftui在同一地图视图中添加多个标记？

这是我的代码：

import SwiftUI
import UIKit
import GoogleMaps

struct MapView: UIViewRepresentable {
    let coordinate: CLLocationCoordinate2D?
    let marker : GMSMarker = GMSMarker()

    func makeUIView(context: Self.Context) -> GMSMapView {
        let camera = GMSCameraPosition.camera(withLatitude: coordinate.latitude, longitude: coordinate.longitude, zoom: 6.0)
        let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
        return mapView
    }

    func updateUIView(_ mapView: GMSMapView, context: Self.Context) {
        marker.position = CLLocationCoordinate2D(latitude: coordinate.latitude, longitude: coordinate.longitude)
        marker.title = "XYZ"
        marker.snippet = "ABCD"
        marker.map = mapView
    }

}

这是我的样本，

struct MapView: UIViewRepresentable {
    let coordinate: CLLocationCoordinate2D
    let cities = [
        [
            "name": "Yangon",
            "lat": 16.8409,
            "long": 96.1735
        ],
        [
            "name": "Mandalay",
            "lat": 21.9588,
            "long": 96.0891
        ]
    ]

    func makeUIView(context: Self.Context) -> GMSMapView {
        let camera = GMSCameraPosition.camera(withLatitude: coordinate.latitude, longitude: coordinate.longitude, zoom: 6.0)
        let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
        return mapView
    }

    func updateUIView(_ mapView: GMSMapView, context: Self.Context) {
        for city in cities {
            let marker : GMSMarker = GMSMarker()
            marker.position = CLLocationCoordinate2D(latitude: city["lat"] as! CLLocationDegrees, longitude: city["long"] as! CLLocationDegrees)
            marker.title = city["name"] as? String
            marker.snippet = "Welcome to \(city["name"] as! String)"
            marker.map = mapView
        }
    }
}
