Yes, here is the code as-is in the Swift file and the schema printed. Appears to only affect Array and Set types, not Dictionary. I attached a snippet demonstrating it. Reported: FB20942577

Not only with previews but it also doesn’t remember whether I have console closed or open

That’s a good idea, I’ve started doing that with some properties. Although I might not do it with all, because I’m unsure if constantly initializing them is efficient. And if I use an array of raw values then I get fault errors something about Objective C array for some reason. As for the protocols, I use them a lot outside of just IDs, which still crashes for me.
