Quite happy to see Servo coming along again. I am still excited for Ladybird and it seems more likely to deliver a truly viable browser sooner.

I am not a Swift dev but I think it has decent memory safety as well. I think it is one of the reasons Ladybird is moving to it. They evaluated Rust and decided it lacked the OOP features they needed.

The C++ that Ladybird writes is also very good. They have their own standard library (written for SerenityOS) which is very modern including memory safety and security. Still C++ though of course.
