title: SwiftUI SceneDelegate Issue
body: <p>Within <code>SceneDelegate.swift</code> the following code is returning the error message <strong>"Use of unresolved identifier 'ContentView'; did you mean 'ContentMode'?".</strong></p>
  
  <pre><code>func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options 
  connectionOptions: UIScene.ConnectionOptions) {
      let window = UIWindow(frame: UIScreen.main.bounds)
      window.rootViewController = UIHostingController(rootView: ContentView())
      self.window = window
      window.makeKeyAndVisible()
  }
  </code></pre>
  
  <p>This error creates a failure in the program build. It's surprising since when I create a new project with the exact same <code>SceneDelegate.swift</code>, there is no issue with ContentView.</p>
  
  <p>If I change ContentView to ContentMode it returns the error <strong>'ContentMode' cannot be constructed because it has no accessible initializers".</strong></p>
  
  <p>Has anyone else had this issue? Just curious where I should start looking or what I have done wrong.</p>
