Rust vs Swift
Rust shows up at 18 of the 252 companies we track, Swift at 6. None have both.
Counts come from DNS, response headers, page source and public job posts; a tool named in a single job post is not counted. They show adoption among companies developers look up, not market share. There is no signed verdict for this pair yet.
