title: Cannot find TestView in scope
body: <p>I am seeing the following error in iOS14, I am not sure if it is a bug or a user error :-)
  I appreciate it is still in beta, so I will post this in the developer forums as well.</p>
  <p>I am seeing the following error come up when I make a macOS app in SwiftUI - when I create the same as an iOS app, the error does not appear.</p>
  <p>Do I need to do something special for macOS apps when it comes to importing SwiftUI modules?</p>
