Now, this response was "not on my bingo card" as the youths say. I find it surprising that Swift would come up on a discussion about JavaScript auth libraries.
Can you tell us more about what you are looking for?
Sorry it was a bit off-topic (not related to Auth.js).
I'm specifically asking about Better-Auth, as I'd love to use it in an iOS app but the client library is all JS. I'd even consider writing my own client library, but there is virtually no documentation on how to do so.
