What programming languages does this skill support?

This skill is specifically optimized for Swift development, focusing on patterns like try!, try?, and do-catch common in iOS and macOS programming.

What logging system does it implement?

It defaults to the AppLog pattern for standardized error reporting, though it can be configured to use your project's specific logging utility.

Is it safe to use on large production codebases?

Yes, it uses targeted Grep searches to identify specific unsafe patterns, allowing for precise, low-risk refactoring across large projects.

How does this prevent application crashes?

By replacing 'try!' (which triggers a crash on failure) with do-catch blocks and fallbacks, it ensures the app remains stable even when operations fail.

Can it automatically fix the errors it finds?

Yes, the skill uses the Edit and Grep tools to refactor unsafe patterns into safe, logged do-catch blocks automatically.

Mobile Development

Audits and refactors unsafe Swift error handling patterns to prevent crashes and improve application observability.

The Error Handling Auditor is designed to harden Swift and iOS applications by identifying and remediating dangerous coding patterns. It scans codebases for 'try!' force unwraps, empty catch blocks, and silent 'try?' failures that can lead to unexpected crashes or untraceable bugs. By automatically refactoring these into robust do-catch blocks and integrating standardized logging via AppLog, this skill ensures that errors are gracefully handled and properly recorded, significantly improving the reliability and maintainability of your mobile applications.
