FirebaseUI 16.1.0

This release introduces support for legacy sign-in recovery flows, separates email/password and email link sign-in configurations, improves localization fallback resiliency, and refines error propagation during account conflicts.

🚀 New Features & API Enhancements

Legacy Sign-In Recovery Flow

• Added support for retrieving alternative sign-in methods for an email address during authentication errors or account conflicts, letting users recover or switch to their active credentials smoothly.
• New Configuration Property: legacyFetchSignInWithEmail: Bool added to AuthConfiguration (defaults to false).
• New Public Models:
  • LegacySignInOption – represents an alternative sign-in method/provider.
  • LegacySignInRecoveryContext – context holding details for alternative sign-in options and unavailable providers.
• New Public API Methods:
  • AuthService.renderLegacyRecoveryButtons(spacing:) -> AnyView – renders buttons for the legacy sign-in recovery options.
• New Public Errors:
  • Added AuthServiceError.legacySignInRecoveryPresented to handle view-state transitions when recovery options are displayed.

Separated Email Sign-In Configurations

• Distinctly split Email/Password and Email Link sign-in configuration methods in AuthService:
  • withEmailSignIn() now strictly enables inline Email & Password sign-in within the AuthPickerView.
  • Introduced withEmailLinkSignIn() and withEmailLinkSignIn(onTap:) to configure and trigger Email Link (Passwordless) sign-in as a distinct option.

🛠️ Behavioral Changes & Bug Fixes

Resilient String Customization & Fallback

• Enhanced StringUtils localization mechanism. If a custom Bundle is supplied via AuthConfiguration(customStringsBundle:) but does not override all strings, the library now seamlessly falls back to the default package strings in Bundle.module rather than rendering empty fields or raw keys.

Improved Conflict & Error Handling

• Standardized the event order in external provider authentication buttons (Apple, Google, Facebook, Twitter, OAuth). The custom accountConflictHandler is now executed before general error reporting (reportError). This prevents resolved/handled account conflicts from bubbling up as generic errors.
• Multi-Factor Authentication (MFA) Management buttons are now hidden automatically if MFA is disabled in AuthConfiguration.
• Resolved potential SwiftUI actor isolation issues by marking the following public view structs with @MainActor:
  • EmailLinkView
  • PasswordRecoveryView
