Can it detect Swift fatal errors?

Yes, it is specifically configured to identify Swift runtime errors such as force-unwrapping nil or misaligned pointer access that often cause immediate crashes.

Does this require a physical device?

This skill is optimized for debugging on physical iOS/iPadOS devices connected to your Mac, providing visibility into logs that are usually difficult to access.

Can it help with Out-of-Memory (OOM) issues?

Yes, the skill identifies Signal 9 (SIGKILL) patterns, which are standard indicators of Jetsam events where the system kills the app due to high memory usage.

How does this skill capture crash logs?

It utilizes 'xcrun devicectl device process launch' with the --console flag to redirect stdout and stderr directly to the Claude interface for real-time analysis.

Diagnoses iOS and iPadOS application crashes by deploying apps with real-time console capture and automated log analysis.

The iOS Crash Debugger skill empowers developers to troubleshoot elusive app crashes on physical devices by leveraging advanced xcrun devicectl commands. It automates the process of building, installing, and launching apps with full console capture (stdout/stderr), allowing for the immediate detection of Swift runtime errors, memory issues (SIGKILL/OOM), and segmentation faults. By providing deep visibility into the app's execution lifecycle without requiring a full Xcode debugger attachment, it streamlines the identification of root causes like misaligned pointers, force-unwrap failures, and signal-based terminations.
