As someone dealing with Swift everyday (and, before that, faster langs like Elixir and Typescript), I can only agree. Sometimes my incremental builds take 20-30 seconds and it feels like a huge toll. Waiting on the CI (which is a weak machine) is up to 25 minutes until the test suite has passed - a large chunk of that being compilation time. Releases take 5-10 minutes.

I really like Swift, but I’d highly appreciate faster compilation times.
