October 2025 - Tidal SDK iOS: Focused on authentication session resilience. Implemented a fix to the token refresh flow so that retryable server or network errors return stored credentials instead of failing, preserving user sessions. Client-side errors continue to trigger logout as designed. This change is captured in commit 55daae43c57b2deaaaa239c8c6888fc80862a903 and applied in tidal-music/tidal-sdk-ios. Overall impact: reduced user disruption during authentication, improved session stability, and lower potential churn. Demonstrates strong iOS client skills, secure credential handling, and robust error handling with retry logic.
