After moving to Xcode 12, my tvOS app now has black backgrounds in all the UITableViews. This happens on a real device (newest Apple TV 4K) as well as in the simulator.
In the Xcode project, all the default settings are used for the UITableView so it should have a transparent background and take on the look of the view it is contained in.
When using a Light appearance, the background is white but should be transparent.
What has happened in the transition from Xcode 11 to Xcode 12?
It looks like you must now explicitly set the background color to clear.
