title: SwiftUI - NavigationLink to go back to previous view
body: <p>I'm testing out SwiftUI by building an app that has a "Settings-View", let's call it ViewB. This view has a list where you can select a language. 
  The first view, ViewA has 2 buttons "Open" or "Select language".</p>
  
  <p>What I want to do is, starting from ViewA, open ViewB, select a language and automatically come back to ViewA. This is what I've done: </p>
  
  <p>ViewA</p>
  
  <pre><code>var body: some View {
      NavigationView {
          VStack(alignment: .center) {
              Button(action: start) {
                  Text("Open")
              }
              NavigationLink(destination: ViewB()) {
                  Text("Change language")
              }
          }
          .sheet(isPresented: $presenting) {
              DemoView(code: self.langugage ?? "SE") { result in }
          }
      }
  }
  </code></pre>
  
  <p>And this is how far I've come on ViewB: </p>
  
  <pre><code>var body: some View {
      List(langs) { item in
          HStack {
              NavigationLink(destination: ViewA(presentingSuccessScreen: self.$isPresentingSuccessScreen, language: item.code)) {
                  Image(item.icon).resizable().frame(width: 40, height: 40)
                  Text(item.market)
              }.frame(height: 64)
          }
          .navigationBarTitle(Text("Select Language"), displayMode: .inline)
          .navigationBarBackButtonHidden(true)
          .navigationBarItems(trailing:
              Button("Cancel") {
                  self.presentationMode.wrappedValue.dismiss()
          })
      }
  }
  </code></pre>
  
  <p>I would like to have the ">" image on the right side of each row, which you get automatically with NavigationList and I want the whole row to be selectable. But by doing it this way, all I get is the destionation view pushing on top of the stack, so If I change language multiple times, I end up with a lot of views on top of each other. </p>
  
  <p>Any help will be appreciated! </p>
