我已经使用MapKit实现了 Apple SwiftUI 教程的略微更改版本。

当我运行它时，我收到错误消息并调整我得到的相应视图的大小：

[SwiftUI] NSHostingView is being laid out reentrantly while rendering its SwiftUI content. This is not supported and the current layout pass will be skipped.

                        let destination = MKMapItem(placemark: MKPlacemark(coordinate: self.location!.coordinates))
                        destination.name = "the car"
                        destination.openInMaps()
                    }
                }
                .frame(width: proxy.size.width, height: proxy.size.height, alignment: .bottomTrailing)
                .offset(x: -10, y: -10)
            }
    )

地图视图结构：

import MapKit
