Question

I want to add a custom navigation button that will look somewhat like this:

Now, I\'ve written a custom BackButton view for this. When applying

Answer 1

Based on other answers here, this is a simplified answer for Option 2 working for me in XCode 11.0:

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

    var body: some View {

        Button(action: {
           self.presentationMode.wrappedValue.dismiss()
        }) {
            Image(systemName: "gobackward").padding()
        }
        .navigationBarHidden(true)

    }
}

Note: To get the NavigationBar to be hidden, I also needed to set and then hide the NavigationBar in ContentView.

struct ContentView: View {
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: DetailView()) {
                    Text("Link").padding()
                }
            } // Main VStack
            .navigationBarTitle("Home")
            .navigationBarHidden(true)

        } //NavigationView
    }
}
