There is an article about this based on a Chris Lattner talk/links to previous HN discussions: https://danielchasehooper.com/posts/why-swift-is-slow/

Wow. I think sometimes you just don't know how things are going to turn out until you use something "in anger", as they say here in the UK. "Let's try using this fancy type-checker in a production language" is reasonable. "Let's overload + so you can combine things easily" is reasonable. "Let's allow you to express different kinds of types as a string" sounds pretty cool too. How could you know the combination of all of those would change a simple expression with an invalid type in it into a 42-second compile time with a cryptic error message, except by actually doing it?

EDIT: Meanwhile, over here in go-land, I just got annoyed that adding a new external authorization library took the average compile time of my 20k project from 7s to 9s.

This is absolutely wild.
