There’s sliced bread, and then Result.publisher

(This is an entry in my technical notebook. There will likely be typos, mistakes, or wider logical leaps — the intent here is to “let others look over my shoulder while I figure things out.”)

Another learning from Adam.

A situation I often find myself in is sketching an operator chain and exercising both the value and failure paths by swapping upstream with Just or Fail, respectively.

And it turns out that Apple added a Combine overlay to Result with the .publisher property that streamlines the two. That is, while all three of Just, Fail, and Result.Publisher have their uses, the latter might be easier to reach for in technical writing. Moreover, it’s a quick way to materialize a throwing function and pipe it downstream.

Or, as I’ll call it going forward—“the ol’ razzle dazzle.”
