Hi all,
I've just tagged WebAuthn Swift 1.0.0 Alpha 1. We're pretty happy with how this has turned out and it covers a significant portion of the WebAuthn spec. I think the API is finalised (baring anything major coming up) and we have a pretty expansive test suite but we need more eyes on it now to put it through its paces.
I'd be happy shipping this in a production app but do be aware that issues may arise as people poke at it. You can see an example integration using Passkeys with Vapor at
But it should work with any server-side Swift framework. There's also a demo site to try it out yourself

(Note that this uses an in-memory DB that may be wiped at any time)
