title: How do you migrate to the new SwiftUI App Protocol?
body: <p>I am working on a SwiftUI app that still has the Scene / App Delegate files and would like to migrate it to the new SwiftUI App Protocol.</p>
  <p>Is this only a matter of deleting the Scene / App Delegate files, then adding my ContentView (Initial View in my case) to the @main struct???</p>
  <p>Thank you!</p>
  <pre><code>@main
  struct TestApp: App {
      var body: some Scene {
          WindowGroup {
              ContentView()
          }
      }
  }
  
  </code></pre>
