Sorry, I wasn’t clear. I wasn’t saying that having it on the same exactly physical line is cleaner, I was saying that having the criteria for the “what I’m iterating” above the loop body and “what I’m doing with those things” inside the loop body is a much cleaner metaphor to me, and one of my favorite bits of Swift. It feels very Swifty to allow the programmer to separate these two concepts nicely.

I don’t care if/how lines are wrapped. In some cases I put the “where” on the next line in my code right now.
