> My intuition *completely* agrees that Swift no longer needs C-style for loops. We have richer, better-structured looping and functional algorithms. That said, one bit of data I’d like to see is how often C-style for loops are actually used in Swift. It’s something a quick crawl through Swift sources on GitHub could establish. If the feature feels anachronistic and is rarely used, it’s a good candidate for removal.

Every time I’ve used a C-style for loop in Swift it was because I forgot that .indices existed. If it’s removed, a fixme pointing that direction might be useful.
