Missing WebAuthn Passkeys Information

[rcw1993]

Describe the content issue:
Hello, the WebAuthn Passkey information for biometric authentication is missing code examples for Swift. Judging by the other program language pages, there are a few others after it missing as well. I have confirmed on Chrome and Safari.
