Kotlin has all of these features and build times don't (noticeably) suffer.

As does Rust.

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.

No it doesn't. Rust doesn't have overloading, or operator overloading, or literal overloading. It literally has none of the pieces that cause the combinatorial explosion in Swift.
