How to Pop to the Root View Using Swiftui

How can I pop to the Root view using SwiftUI?

Setting the view modifier isDetailLink to false on a NavigationLink is the key to getting pop-to-root to work. isDetailLink is true by default and is adaptive to the containing View. On iPad landscape for example, a Split view is separated and isDetailLink ensures the destination view will be shown on the right-hand side. Setting isDetailLink to false consequently means that the destination view will always be pushed onto the navigation stack; thus can always be popped off.

Along with setting isDetailLink to false on NavigationLink, pass the isActive binding to each subsequent destination view. At last when you want to pop to the root view, set the value to false and it will automatically pop everything off:

import SwiftUI

struct ContentView: View {
    @State var isActive : Bool = false

    var body: some View {
        NavigationView {
            NavigationLink(
                destination: ContentView2(rootIsActive: self.$isActive),
                isActive: self.$isActive
            ) {
                Text("Hello, World!")
            }
            .isDetailLink(false)
            .navigationBarTitle("Root")
        }
    }
}

struct ContentView2: View {
    @Binding var rootIsActive : Bool

    var body: some View {
        NavigationLink(destination: ContentView3(shouldPopToRootView: self.$rootIsActive)) {
            Text("Hello, World #2!")
        }
        .isDetailLink(false)
        .navigationBarTitle("Two")
    }
}

struct ContentView3: View {
    @Binding var shouldPopToRootView : Bool

    var body: some View {
        VStack {
            Text("Hello, World #3!")
            Button (action: { self.shouldPopToRootView = false } ){
                Text("Pop to root")
            }
        }.navigationBarTitle("Three")
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

SwiftUI 2 pop to root view with no Scene delegate

A possible solution is to create an ObservableObject that is responsible for routing:

enum AppView {
    case login, main
}

class ViewRouter: ObservableObject {
    // here you can decide which view to show at launch
    @Published var currentView: AppView = .login
}

Then, you can inject this ViewRouter as an EnvironmentObject to the root view:

@main
struct TestApp: App {
    @StateObject private var viewRouter = ViewRouter()
    
    var body: some Scene {
        WindowGroup {
            RootView()
                .environmentObject(viewRouter)
        }
    }
}

Now you can change the current view from any view:

struct RootView: View {
    @EnvironmentObject private var viewRouter: ViewRouter
    
    var body: some View {
        VStack {
            if viewRouter.currentView == .login {
                LoginView()
            } else if viewRouter.currentView == .main {
                MainView()
            }
        }
    }
}

struct LoginView: View {
    @EnvironmentObject private var viewRouter: ViewRouter
    
    var body: some View {
        VStack {
            Text("Login View")
            Button("Log in") {
                viewRouter.currentView = .main
            }
        }
    }
}

struct MainView: View {
    @EnvironmentObject private var viewRouter: ViewRouter
    
    var body: some View {
        VStack {
            Text("Main View")
            Button("Log out") {
                viewRouter.currentView = .login
            }
        }
    }
}

SwiftUI ColorPicker cause pop to root view

NavigationView in each tab instead of outside the TabView

Pop to root view using Tab Bar in SwiftUI

We can use tab bar selection binding to get the selected index. On this binding we can check if the tab is already selected then pop to root for navigation on selection.

struct ContentView: View {

@State var showingDetail = false
@State var selectedIndex:Int = 0

var selectionBinding: Binding<Int> { Binding(
    get: {
        self.selectedIndex
    },
    set: {
        if $0 == self.selectedIndex && $0 == 0 && showingDetail {
            print("Pop to root view for first tab!!")
            showingDetail = false
        }
        self.selectedIndex = $0
    }
)}

var body: some View {
    
    TabView(selection:selectionBinding) {
        NavigationView {
            VStack {
                Text("First View")
                NavigationLink(destination: DetailView(), isActive: $showingDetail) {
                    Text("Go to detail")
                }
            }
        }
        .tabItem { Text("First") }.tag(0)
        
        Text("Second View")
            .tabItem { Text("Second") }.tag(1)
    }
  }
}

struct DetailView: View {
 var body: some View {
    Text("Detail")
  }
}
