I’m sort of in two minds. On paper, I think for greenfield projects data-race safety checking looks great. If I switch to thinking about my day job, I know we will likely never adopt Swift 6 for some of our components because they’d need to basically be rewritten, at which point we’d probably consider something more cross platform like Rust or Kotlin. So despite liking the feature on paper, I feel like the overhead it introduces in practice is kind of pushing me away from the language.

It’s hard to say at this point though, adoption might get a lot easier with subsequent point releases.
