SwiftUI导航栏已切断

Question

我最近更新了Xcode，由于某种原因，现在在模拟器中（以及在设备上），我的SwiftUI视图上的导航栏被切断，如下图所示：

我没有更改任何代码，所以我想知道到底发生了什么。该视图的代码供参考：

    init() {
        viewModel = EventsViewModel()
        coloredNavAppearance.configureWithOpaqueBackground()

        coloredNavAppearance.backgroundColor = ColorCodes.darkGrey.uicolor()
        coloredNavAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
        coloredNavAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]

        UINavigationBar.appearance().standardAppearance = coloredNavAppearance
        UINavigationBar.appearance().scrollEdgeAppearance = coloredNavAppearance

        UINavigationBar.appearance().tintColor = .white

        UITableView.appearance().separatorStyle = .none
    }

    var body: some View {
        NavigationView {
            ZStack {
                ColorCodes.darkGrey.color()
                    .edgesIgnoringSafeArea(.all)
                VStack {
                    if viewModel.eventViewModels.isEmpty {

                        Text("No events are active yet. Click the plus button to purchase an event.").foregroundColor(.white).font(.custom("Segoe UI", size: 17))
                    }else {
                        List{

                            ForEach(viewModel.eventViewModels, id: \.id) { eventViewModel in
                                EventRow(viewModel: eventViewModel)
                            }.listRowBackground(ColorCodes.darkGrey.color())
                        }

                    }
                }
                .navigationBarTitle(Text("Active Events"), displayMode: .large)
                .navigationBarItems(trailing:
                    Button(action:  {
                        //show add event modal
                        self.viewModel.showAddEventModal.toggle()
                    }) {
                        Image("plus")
                    }
                )
                .alert(isPresented: $viewModel.showAlert) {
                    Alert(title: Text("Error"), message: Text(viewModel.errorMessage), dismissButton: .default(Text("Ok")))
                }
                .font(.custom("Segoe UI", size: 17))
                .sheet(isPresented: $viewModel.showAddEventModal) {
                        AddEventView(viewModel: AddEventViewModel())
                }
            }
        }
    }

我的确在班级的初始化过程中有一些自定义的导航栏外观登录名，但这在以前是非常好的。这是否发生在其他任何人身上，也没有人找到或找到解决方法吗？

您通过忽略顶部边缘安全区域（因为它是inside导航视图）来强行移动它

ZStack {
    ColorCodes.darkGrey.color()
        .edgesIgnoringSafeArea(.all) // << reason !!!

删除此行，或仅使用.bottom，然后使用for NavigationView代替内容。经过Xcode 11.4 / iOS 13.4的测试]
