One more time: Swift does not have exceptions at all (checked or not). You are comparing apples and oranges here, based on a surface similarity in syntax (keywords like “try” and “catch”), which indicates you haven’t paid attention to what the actual semantics are. If you want to make credible arguments about error handling, you’ll need a better understanding of it.

I note that Go — a language you profess to like a lot — has no exceptions either, and its error handling support is much more primitive and clumsy to use than Swift’s. (I say this having spent about a man-year coding in Go.)

Go is pretty much the ultimate in that philosophy — Rob Pike and others are very up-front that they know what features are best and they will decide the right way to do things and if you disagree you are wrong. (Pike’s blog post about error handling from about a year ago is a great example of this arrogance.) I see the Swift developers being a lot more open about this, instituting a very open process for proposing and debating changes.
