I know they have said that. But it feels a bit strange to me to continue to develop in C++ then, if they eventually will have to rewrite everything in Swift. Wouldn't it be better to switch language sooner rather than later in that case?

Or maybe it doesn't have to take so much time to do a rewrite if an AI does it. But then I also wonder why not do it now, rather than wait.

That is the plan, but they are stalled on that effort by difficulties getting Swift's memory model (reference counting) to play nice with Ladybird's (garbage collection)

I think there was some work with the Swift team at Apple to fix this but there haven't been any updates in months

That is very good news!

I've used Swift a bunch for hobby projects, and the two things that suck about it are:

1. XCode

2. Compile times

I would assume if you're coming from C++ or Rust the compile time issues aren't really something you notice anyway :P

If I remember correctly, the guy behind it used to work at Apple, maybe that has to do something with it?

I know that that’s the plan, but I believe it when I see it. Mozilla invented entire language features for Rust based on Servo’s needs. It’s doubtful whether a language like Swift, which is used mostly for high-level UI code, has what it takes to serve as the foundation of a browser engine.
