title: SwiftUI: Preload View without displaying
body: <p>I'd like to &quot;preload&quot; a view (including a SKScene) to gather the bounds of the display area of this scene.
  The size information is needed to precompute additional data, the computation should be done in the background while displaying the home screen (different to the screen containing the SKScene).</p>
  <p>Q: It it possible to preload a view and if so, how?</p>
  <p>Thanks,
  J.</p>
