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…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# iOS Production Error Observability

Production-grade skill for eliminating silent failures in iOS apps. Most production errors don't crash — they vanish through `try?`, `Task {}`, `.replaceError()`, and `print()`-only catch blocks.

AI coding assistants systematically generate observability-blind code because their training data is overwhelmingly tutorial code: `print(error)` in every catch block, `try?` everywhere, `Task {}` with no error handling, no crash SDK integration, no privacy annotations, and zero consideration for MetricKit or PII compliance. This skill intercepts those patterns and enforces observable error handling from the start.

**Logging is the key to debugging.** When a bug appears in production across thousands of devices, you can't attach a debugger. Remote logging through crash reporting SDKs transforms a 3-day debugging mystery into a 15-minute investigation. This skill enforces observable error handling: every error is logged with `os.Logger` (with privacy annotations), reported to a remote crash/analytics SDK, and surfaced to the user or operator.

Three non-negotiable rules:
1. **No `print()` in production code** — use `Logger` with privacy annotations

How to install

The exact contents, by fingerprint
mdr add rusel95/ios-agent-skills/ios-logging@sha256:4f44a3fa6f428f19

The line at the top of this page pins the label v1.0.3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
