SwiftUI navigationView getting back only from second screen and not from the next ones

Question

I've got a problem with SwiftUI. Basically this is my view graph:

View1 -> View2 -> View3 -> etc.

Now i want to show a back button in View2, but when user gets to view 3, it shouldn't be visible. I tried hiding and removing items, but still i can see back button on next views which will get me back to View1.

Answer 1

As i was unable to do this the pure and nice way, i created a custom button, with dismiss action, which has content and the action works if only property isShowingButton is true, then on getting to next view i toggle it to false. It works, maybe not nicest way but works. If somehow someone knows a better way to solve it, i'd be grateful

Without seeing your Code it's quite hard to tell where the issue is.

However the following Code is working for me

struct ContentView: View {

    var body: some View {
        NavigationView {
            FirstView()
        }
    }
}

struct FirstView: View {

    var body: some View {
        NavigationLink(destination: SecondView()
        ) {
            Text("Go to Second View")

        }
        .navigationBarTitle("FirstView", displayMode: .inline)

    }
}

struct SecondView: View {

    var body: some View {
        NavigationLink(destination: ThirdView().navigationBarBackButtonHidden(true)
        ) {
            Text("Go to Third View")
        }
        .navigationBarTitle("SecondView", displayMode: .inline)
    }
}

struct ThirdView: View {

    var body: some View {
            Text("Third View without Back Button")
        .navigationBarTitle("Third View", displayMode: .inline)
    }
}

Answer 3

When navigating to View 3 you need to add .navigationBarBackButtonHidden(true) to the NagivationLink

struct ViewTwo: View {

var body: some View {
    NavigationLink(destination: SecondView().navigationBarBackButtonHidden(true)
    ) {
        Text("Go to View 3")

    }
    .navigationBarTitle("View 2", displayMode: .inline)

}

}
