swift – How can I hide the navigation back button in SwiftUI?

Maybe:

.navigationBarBackButtonHidden(true)

I tried placing .navigationBarBackButtonHidden(true) in a few different places. This is the behaviour I observed.

struct PageOne: View {
    var body: some View {
        NavigationView {
            VStack{
                NavigationLink(destination: PageTwo()){
                    Text("Go to Page Two")
                }
            }
        }
    }
}

// Hide from page 2 -> page 1
struct PageTwo: View {
    var body: some View {
        VStack{
            NavigationLink(destination: PageThree()){
                Text("Go to Page Three")
            }.navigationBarBackButtonHidden(true)
        }
    }
}

// Hide from page 3 -> page 2 (Same behaviour as Kheldar's answer above)
struct PageTwo: View {
    var body: some View {
        VStack{
            NavigationLink(destination: PageThree().navigationBarBackButtonHidden(true)){
                Text("Go to Page Three")
            }
        }
    }
}


struct PageThree: View {
    var body: some View {
        Text("Hello!")
    }
}

Using via a navigationLink

NavigationLink(destination: SomePage().navigationBarBackButtonHidden(true), tag: 1, selection: $selection) {
    //..
}

The .navigationBarBackButtonHidden(true) will hide the back button.

I encountered a situation where I couldn’t get the .navigationBarBackButtonHidden(true) to work until I placed it on the View that I embedded within the NavigationLink itself.

NavigationLink(destination:MyView(stuff: aStuff, onDismiss: {})) {
         HStack {
             Text(aStuff.interestingText)
         }
} // <- used to set it here, doesn't work for me

with:

struct MyView: View {

    var aStuff: Stuff
    var onDismiss: () -> Void

    var body: some View {
          VStack(alignment: .leading) {
               Button(action: self.onDismiss) {
                   Image(systemName: "chevron.left.circle")
               }
               CoolAnimatedStuffDisplayer(stuff: aStuff)
          }
          .navigationBarBackButtonHidden(true) // <--- works here
    }
}
