NSLog vs os_log for Deployment‑Failure Diagnostics: Synchronous vs Asynchronous Logging
Goal Determine the most reliable logging strategy for diagnosing a failed iOS/macOS deployment, focusing on visibility of error details, performance impact on the UI thread, and privacy controls. Constraints Performance: os_log writes asynchronously; NSLog writes synchronously to stderr. Privacy: os_log supports compile‑time masking that can hide sensitive d
