In iOS, storyboards can be used as the launch screen instead of static images. I am looking for a way to do this with tvOS as well, but I don't see the option. Is there a way to do so?
You can now use storyboards, in fact as of tvOS 13.0 it's the preferred method.
It will automatically be set up for you on new projects. For old projects create your launch image story board, make sure "Is initial view controller" is checked in the inspector window. After setting up your storyboard under "Project Setting -> General -> Launch Screen File" you will be able to select your storyboard as the launch file to use.
