From what I've heard Rust has serious build-time issues as well, mostly because of it's inability to perform separate compilation of generic code. Unlike Swift, Rust specializes everything at compile-time, similar to C++ templates.

That's not exactly true, while that is usually what Rust people write, you can choose to have stuff not monomorphized. I'm also not exactly sure what you mean by "separate" here.

As usual, compile times depend on what you're used to. It is something we're working on improving though; we want it to be very fast! We expect incremental recompilation to move out of nightly soonish; that will help quite a bit.
