Thanks to Quinn for pointing out that connecting via networking includes going over USB! In my case, the slowness was indeed due to WiFi/Bluetooth. Given that USB is effectively faster, why doesn't Apple make it to connect via the fastest network by default? Or, at least, give developers an option to pick which way to go.

This is very helpful! It's tricky to find. I have a related question. How do we find other info such as attestationPreference through this interface? Is there a way to ASAuthorizationPublicKeyCredentialRegistrationRequest? I don't seem to see how we can achieve this through ASPasskeyCredentialRequest in prepareInterface(forPasskeyRegistration:) for iOS. A more broader question is: do we have access to the WebAuthn extensions in third-party passkey manager? Thanks!

I agree with you that the attestation as it stands right now does not serve a useful purpose in the case of passkeys and should be improved upon. However, shouldn't Apple refrain from tampering with how attestations are used in the middle? With the advent of third-party credential provider extension, there may be some attestation types other than "none" that have a sensible use. For Apple to prevent such uses outright does not seem to be WebAuthn specification complaint either.
