I have nowhere found any mentioning of changing styles like this. Any idea how to achieve this

问题 I have a project written in Swift for tvOS . Now I found a great TVML-document that I want to add in my project. Tell me please if there are any possible ways to do it?

问题 Has anybody figured out how to get motion events working with the new apple TV remote? Thanks.
