swiftui-navigationlink

问题 I am using GMSMapView with SwiftUI, in map-view I have to display some markers with lat and long. Upon clicking any marker I have to Move to another view. I am doing this by putting MapView in NavigationLink . This thing is working fine By using code. NavigationView { NavigationLink(destination: Text(""), isActive: $abc) { MapView().edgesIgnoringSafeArea(.all) } } And the issue is NavigationLink , after putting mapview in NavigationLink every-time when i interact with map, white overlay

问题 I have list of Account s that each of them has a detail page and they are connected through @Binding in the AccountDetailView . Current code work well, updates are fine. No problem at all. However when I added the onDelete modifier to the ForEach below and tried swipe to delete gesture in app, it crashes and says Fatal Error: Index out of range twice. I made some search and learned that ForEach somehow does not get notified -or ignores it, idk much detail- and looks for the last index of the

问题 I want to build a very simple iOS 14 sidebar using SwiftUI. The setup is quite simple, I have three views HomeView , LibraryView and SettingsView and an enum representing each screen. enum Screen: Hashable { case home, library, settings } My end-goal is to automatically switch between a tab view and a sidebar depending on the size class but some things don't quite work as expected. The global state is owned by the MainNavigationView , which is also the root view for my WindowGroup . struct

问题 I've added a .toolbar to the top level of a NavigationView that will eventually be used to select items in a list without using swipe gestures (up button, down button, etc.). I also have a .navigationBar going on, to access other views for Account and Settings. For the most part it's looking really good, but when I follow a NavigationLink (in .navigationBarItems) within NavigationView, and then use the built-in back navigation , my .toolbar disappears from the top level.

问题 Let us consider the situation when you have ContentView and DestinationView . Both of them depend on some shared data, that typically lies inside the @ObservedObject var viewModel , that you pass from parent to child either via @EnvironmentObject or directly inside init() .

I found this solution from MScottWaller: iOS SwiftUI: pop or dismiss view programmatically Unfortunately, in my case it does not work: struct MasterView: View { @State private var showDetail = false var body: some View { VStack { Text("MasterView") .navigationBarItems(trailing: HStack { NavigationLink(destination: DetailView
