July 2025 monthly summary for AzureAD/microsoft-authentication-library-common-for-objc. Focused on strengthening SSO state visibility and reliability by introducing an explicit PSSO registration state flag in MSIDExternalSSOContext. This foundation improves management of PSSO authentication flows, reduces edge-case failures, and enhances diagnosability. Delivered a new boolean isPSSORegistration flag wired into the SSO context, accompanying code change to track when PSSO registration is in progress. Commit: 4eea7de788033d807faf8d0fd9fa3681a5392588.

June 2025: Focused on strengthening privacy and robustness of camera permission handling in the embedded WebView used for authentication. Delivered a targeted feature that consolidates two commits to ensure permission prompts apply only to camera media types by aligning general and SDM-specific camera consent flags. The changes enhance user privacy, reduce prompt fatigue, and improve reliability of the authentication flow across iOS.

February 2025 (AzureAD/microsoft-authentication-library-common-for-objc): Delivered reliability and privacy improvements to embedded webview flows. Key features include improvements to camera consent prompt handling by removing a global variable and driving behavior via user defaults, with explicit constants for user defaults keys to honor user preferences. Major bugs fixed include ensuring the webview permission decision handler is always invoked, eliminating edge cases where the completion handler could be skipped. Overall impact includes a smoother user experience for consent prompts, reduced edge-case failures, and improved maintainability of permission logic. Technologies/skills demonstrated include refactoring for configuration-driven behavior, robust conditional logic, constants-driven configuration, and improved testability of iOS SDK permission flows.
