Add Accessibility Label Support to Toolkit Authenticator for UI Testing

[douglaswsilva]

Description

Our UI tests for the ArcGIS Flight sign-in flow require reliable accessibility identifiers/labels on the Toolkit Authenticator UI components. Currently, the Toolkit Authenticator does not expose accessibility labels for key elements (e.g., username field, password field, sign-in button, cancel button), making it difficult to target them in automated UI tests.

Problem

• The authenticator’s views do not include stable accessibility labels or identifiers.
• XCTest UI tests must rely on text or view hierarchy, which is brittle and may break with design or localization changes.

Requested Enhancement

Add accessibility labels/identifiers to all interactive elements inside the Toolkit Authenticator, including but not limited to:

• Username text field
• Password text field
• Sign-in button
• Cancel / Dismiss button
• Any error or status messages presented during sign-in

Identifiers should be stable, human-readable, and appropriate for use in automated UI testing.

Benefits

• Enables robust, deterministic sign-in UI tests across teams.
• Improves accessibility compliance for users relying on VoiceOver.
• Provides unified and testable behavior across apps that depend on the Toolkit.
