Navigating From "NavigationViews" to "TabViews"

Forums > SwiftUI

I don't really have code to share, but the idea and question is pretty simple, I just cannot seem to find the right way to do it.

I have a SaaS-type application where a user signs up, receives a Web Token which goes into the UserDefaults. Once this is complete, and that token is present, I want to take the user to a TabView with the main menu stuff and they can begin using the app.

What's the best way to essentially break away from the NavigationView flow where a user creates their account, and then drop them into the TabView where they can begin using the app.

I tried:

On the final NavigationView screen, the user finishes adding all their account information, the token comes back and gets stored, and then I render a "Continue" button. The action on this button calls MainTabView() to try and kick-off the new flow of using the app's main features.

All that happens is I receive this error:

Result of 'MainTabView' initializer is unused

Any insights?


Hi Thomas,

Have you tried a .fullScreenCover. This covers the TabView.

here some dummy code

struct ContentView: View {
    @AppStorage("token") var noToken = true

    var body: some View {
        TabView {
                .tabItem {
                .tabItem {
        .fullScreenCover(isPresented: $noToken) {
            TokenView(noToken: $noToken)

and TokenView

struct TokenView: View {
    @AppStorage("tokenName") var tokenName = ""
    @Binding var noToken: Bool

    var body: some View {
        VStack {
            TextField("Enter Token", text: $tokenName)

            Button("Submit") {
                noToken = false

PS you should not store token in UserDefaults/@AppStorage etc. You should really store it in KeyChain as this is encrypted.
