In xcode, and tvos, the 3D parallax icons in the asset catalog are shown as image stacks. But this is not the case with the so called top shelf image.
Is it possible to convert the top shelf image to a multi layer image stack in xcode?
Only content that is focusable is multilayered and then you need to provide several of them.
There are 3 top shelf types, but unfortunately none of them fit your needs.
You can read more about them in apple tv human interface guide lines.
1) single, static top shelf image
Provide a visually rich static image. Your app’s static top shelf image is used when dynamic content isn’t provided or is unavailable. Use it as an opportunity to highlight your brand.
Don’t imply interactivity in a static image. The static top shelf image isn’t focusable, so it shouldn't include elements that make it appear interactive.
2) "Dynamic Content Layouts" - "Sectioned Content Row"
this is for content similar to portrait movie posters. those can be multilayered, but:
Provide enough content to constitute a complete row. At a minimum, load enough images in a sectioned content row to span the full width of the screen.
3) "Dynamic Content Layouts" - "Scrolling Inset Banner"
this is for content similat to wide screen advertising banners. those can be multilayered, but:
A minimum of three images is recommended for a scrolling banner to feel effective.
