Build iOS sign-in with secure credential handling.
Guides implementation of iOS sign-in and local re-authentication flows with secure credential handling.
When to use it
Use when building iOS authentication, including Sign in with Apple, passkeys, OAuth, Password AutoFill, token validation, or biometric re-authentication.
It changes how the agent implements iOS authentication, requiring credential-state checks, server validation, and secure token storage.
What you provide
The implementation guidance uses the AuthenticationServices framework for iOS authentication.
The biometric re-authentication guidance uses LAContext from LocalAuthentication.
Sign in with Apple implementation requires adding its capability in Xcode before using the APIs.
Routes deep security work, including Keychain architecture, cryptography, and certificate trust, to swift-security; an installation requirement is unstated.
