Disable swipe-back for a NavigationLink SwiftUI

Question

How can I disable the swipe-back gesture in SwiftUI? The child view should only be dismissed with a back-button.

Answer 1

By hiding the back-button in the navigation bar, the swipe-back gesture is disabled. You can set a custom back-button with .navigationBarItems()

struct ContentView: View {
    var body: some View {
        NavigationView{
            List{
                NavigationLink(destination: Text("You can swipe back")){
                    Text("Child 1")
                }
                NavigationLink(destination: ChildView()){
                    Text("Child 2")
                }
            }
        }
    }
}

struct ChildView: View{
    @Environment(\.presentationMode) var presentationMode

    var body:some View{
        Text("You cannot swipe back")
            .navigationBarBackButtonHidden(true)
            .navigationBarItems(leading: Button("Back"){self.presentationMode.wrappedValue.dismiss()})
    }
}
