Ah right another thing copied from swift.

  I think a lot of languages implemented this before Swift did. Some MLs (among them OCaml), Haskell, Reason, Elm, Rust. So crediting Swift for this is not fair.

  The fact that you were introduced to concept X by language Y rarely means that X was invented by Y.

  It's actually a fairly old method, that's recently gained popularity as functional programming interest increases.

    I think monadic do comes from Haskell and its ancestors.

  I'm pretty sure monadic error handling came from some ML

  I’ve finally reached the age where I was using something before a language that ‘copied’ it even existed! This was around in Haskell before Swift existed.
