Xcode Debugging

概要

Xcode Debugging provides a battle-tested framework for troubleshooting iOS and macOS development environments, prioritizing system diagnostics over code changes to resolve the 80% of issues caused by environment instability. It helps developers identify and fix "mysterious" build failures, stale caches, and simulator malfunctions by providing automated checks for Derived Data, active processes, and simulator states. By following its structured decision trees and recovery workflows, developers can significantly reduce time wasted on phantom bugs, ensuring that their development environment remains clean and predictable.

主な機能

• 61 GitHub stars

ユースケース

• Resolving 'Unable to boot simulator' or 'BUILD FAILED' errors with no clear code cause
• Fixing 'phantom' build errors where old code executes despite new changes and restarts
• Cleaning up developer environments when Xcode performance degrades or tests hang indefinitely
