如何在SwiftUI MapKit的updateUIView中添加".setRegion“？

struct MapView: UIViewRepresentable {
    // 在这里定义你需要的属性，例如地图的中心坐标和缩放级别
    @Binding var centerCoordinate: CLLocationCoordinate2D
    @Binding var span: MKCoordinateSpan

    // 实现makeUIView方法，创建并返回一个MKMapView实例
    func makeUIView(context: Context) -> MKMapView {
        return MKMapView()
    }

    // 实现updateUIView方法，在这里进行地图的设置
    func updateUIView(_ uiView: MKMapView, context: Context) {
        // 设置地图的中心坐标和缩放级别
        let region = MKCoordinateRegion(center: centerCoordinate, span: span)
        uiView.setRegion(region, animated: true)
    }
}

struct ContentView: View {
    @State private var centerCoordinate = CLLocationCoordinate2D(latitude: 37.331516, longitude: -122.030028)
    @State private var span = MKCoordinateSpan(latitudeDelta: 0.2, longitudeDelta: 0.2)

    var body: some View {
        MapView(centerCoordinate: $centerCoordinate, span: $span)
    }
}
