Ios Logging

Category: General  ·  Sub-category: hello-world-templates  ·  Last updated:
type:audit
Enterprise skill for iOS production error observability and logging (iOS 15+, Swift 5.5+). The trigger is OBSERVABILITY intent — the user wants errors captured and visible in production, not just handled. Use when: adding os.Logger or replacing print() with structured logging; setting up or integrating a crash SDK (Sentry, Crashlytics, PostHog); auditing error handling for silent failures (catch blocks with no Logger/ErrorReporter call, try? on network/auth/payment operations, Task {} with no do-catch, Combine .replaceError() killing error visibility); adding privacy annotations to logs; integrating MetricKit for OOM/hang detection; or asking why errors are disappearing silently in production. Also use when reviewing any catch block, try?, or Task {} specifically to ensure errors reach a remote crash reporting service — not just for writing error handling in general.
