Hello, I downloaded the Swift Playground application on my macbook, I launch any lesson, but no animation is played in the right window, just the blue screen is blank. Instead, an error appears There was a problem running this page. Check your code for problems. If you are stuck, start over to delete all of you changes on this page and try again. https://drive.google.com/open?id=1OPdiEkgMTWTwhW3g_bf-SdWE0MqTZ0bs
And this is the error I have the same problem. I think it might be a GPU problem. Which model of macbook Pro are you using? I personaly use the 2008 model with a patcher for having Catalina and I think that this happens because of the old GPU but if you have a newer model and you also having this problem, something else happens.
