I was using Sierra for a while and the Xcode simulator works well - fast and furious. After updating to Catalina (why the hell i did that :( ) - xcode simulator started to work very slow. Especially animation. Especially for tvOS.
I using MacBook Pro (13-inch, Mid 2012).
Why and how to fix that?
P.S. Slow animations is switched off. Graphics quality override is Low Quality.
