Getting an error "iOS simulator needs xcode12"???

I have no idea what this error is or what Xcode is or why I'm being told anything about a "simulator". The error occurred when I was watching ads on a game (for free in game currency).

I have never been able to attach an image here in the forums so here is the full text of error:

"Software update needed
