Usually, in the Top Shelf target the value for CFBundleDisplayName is TopShelf (for example, in PopcornTimeTV). What value should I use for CFBundleDisplayName? Where can I see this value in the Top Shelf?
The CFBundleDisplayName for a top-shelf extension is not visible to the user on the Apple TV device.
You can use any value you like. I use TopShelfExtension. But as you suggested in your post: TopShelf would also work just fine.
