Pop multiple views off a navigation stack

Forums > SwiftUI

I have a tabbed view where one of the tabs takes the user through a number of "Add Item" screens, which are part of a Navigation Stack. The general workflow is as follows:

Tab - Add Item Home -> Add Item selected -> Enter item name (Screen #1) -> Next -> Enter Item details (Screen #2) -> Next -> Enter Item details (Screen #3) -> Done

When the user selects Done I would like to pop all of teh views off the navigation stack and return to the 'Add Item Home' screen. I know I can use

 @Environment(\.presentationMode) var mode: Binding<PresentationMode>

combined with

self.mode.wrappedValue.dismiss()

to dismiss one screen (the equivalent of pressing back) but how do I pop all views from Navigation stack?

I too, wonder if there's a way to go about doing this without just rendering a view programmatically.

Right now, I just have an if/else in my code that wraps the whole thing...

if (self.showHomeView) {
  HomeView()
} else {
  // Some other view that is nested deeply in my app but when this page is done I want to go back to the home view
  VStack {
    Text("Hello world")
  }
}

Xcode 13 beta 3 self.mode.wrappedValue.dismiss() pop to the root not single. For example login->home->detail->subdetails( Using NavigationView and NavigationLink ). if i execute code on subdetails screen. It's pop to login. Its very strange.

Try NavigationViewKit https://github.com/fatbobman/NavigationViewKit

import NavigationViewKit
NavigationView {
            List(0..<10) { _ in
                NavigationLink("abc", destination: DetailView())
            }
        }
        .navigationViewManager(for: "nv1", afterBackDo: {print("back to root") })

in any view in NavigationView

@Environment(\.navigationManager) var nvmanager         

Button("back to root view") {
    nvmanager.wrappedValue.popToRoot(tag:"nv1"){
             print("other back")
           }
}

You can also call it through NotificationCenter without calling it in the view

let backToRootItem = NavigationViewManager.BackToRootItem(tag: "nv1", animated: false, action: {})
NotificationCenter.default.post(name: .NavigationViewManagerBackToRoot, object: backToRootItem)
