I'll see if I can find it. I don't remember the specifics on rust, but it sounded like they gave it a fair shot. It was basically the one to beat until they figured out it wasn't going to work. The decision to adopt Swift wasn't made on a whim and, frankly, I'm skeptical it will happen any time soon, if ever. I think it's one of those situations where they want to make it more accessible to a next generation of developers the same way Linux is adopting rust. Swift is actually a really nice language, despite being associated primarily with Apple. It would be cool to see higher adoption.

Ladybird has an interesting way of documenting web standards in code. They put a link to the reference doc at the top of a function and then each rule in a comment where it is implemented. It's very easy to follow and good quality code. Another project I recall having high quality code was KHTML. Not coincidentally, Andreas Kling worked on that one too.

There are examples here: https://github.com/LadybirdBrowser/ladybird/tree/master/Libr...

Anyway, the point is what they are doing is working well and Swift won't be ready for a while. If it ever happens, it won't be a rewrite. It'll more likely be a situation where it's written in both the same way Linux is both C and rust.

Andreas has said that in some video I watched at some point, can't pinpoint it, but I can confirm jm4 didn't make it up
