title: What is the alternative for SwiftUI of UIKit's "pushViewController" in a barButtonItem
body: <p>I'm working on a very simple app in SwiftUI and I have managed to create a NavigationButton for my List that takes me to the DetailViewController.
  In the up right corner I wanted to have a "+" button to add things to my List:</p>
  
  <pre><code>navigationBarItems(trailing:
                      NavigationButton(destination: DetailVC()) {
                          Image(systemName: "plus")
                              .resizable()
                              .frame(width: 20, height: 20)
                      }
  )
  </code></pre>
  
  <p>The problem is that when I tap on the button it doesn't navigate to my DetailVC.</p>
  
  <p>I also tried this: </p>
  
  <pre><code>.navigationBarItems(trailing:
                      PresentationButton(destination: DetailVC()) {
                          Image(systemName: "plus")
                              .resizable()
                              .frame(width: 20, height: 20)
                      }
  )
  </code></pre>
  
  <p>With this code the problem is that it doesn't present the DetailVC with a "Back" button, but it shows up from the bottom and there is no way to go back in my ContentView</p>
  
  <p>What is the correct item to put in the navigation bar to navigate correctly? </p>
  
  <p>Thank you, Nico</p>
