Most of the author's frustration was due to lack of good feedback from Swift.

Like, how can it run a command that has an `async` main despite the fact that you didn't extend the async version of command?? That should've been an error (e.g. "bro, you cannot have an async main in this class, you need the Async version of this class which is called AsyncWhatever").

Not awaiting on an async function should be at least a warning. Another frustrating lack of feedback: it just lets you run it and nothing happens.

The version thing: it should show all possible variants in the enum, even the ones you should not be able to use, and then when you try using it, show an error saying "you need to change the version of this file to at least blah to use this". Why can't the Swift LSP do that? Apple has a trillion dollars, they can afford polishing their stuff.

The author is used to Rust, which would've made it very clear what was wrong in all cases.

Swift, being as modern as Rust, should be doing better than that. Languages that fail to give you proper error messages and warnings are just not worth it: just one of these "wtf is going on?" moments can cost you hours. Just use a better language if you can.
