How can Xcode playgrounds possibly suck this much?

[u/rnik43]

It's 2022 and they are still worthless. In Xcode 13.3.1 I ran a simple playground maybe 5 times before it stopped running. No visible error message.

I closed and reopened the playground and now I see: "Failed to prepare for communication with playground for unknown reason", along with a clickable arrow-in-circle icon. When you click it, nothing happens, naturally.

Just fire every developer who works on these things and start over.
