Debugging & Troubleshooting ​

Systematic debugging strategies to solve issues faster and prevent common problems before they happen.

Skills ​

  • Accessibility Debugging – WCAG compliance, VoiceOver testing, Dynamic Type support, App Store Review preparation

    • "App Store rejected my app for VoiceOver issues. How do I fix missing labels?"
    • "How do I test my app for color contrast and Dynamic Type support?"
    • Command: /audit-accessibility for quick WCAG compliance scanning

  • Xcode Debugging – Environment-first diagnostics for mysterious Xcode issues, prevents 30+ minute rabbit holes

    • "My build is failing with 'BUILD FAILED' but no error details. I haven't changed anything."
    • "Build succeeds but old code is executing. I restarted Xcode but it still happens."

  • Memory Debugging – Systematic leak diagnosis with 5 patterns covering 90% of real-world issues

    • "My app crashes after 10-15 minutes of use with no error messages. How do I find the leak?"
    • "View controllers don't deallocate after dismiss. How do I find the retain cycle?"
    • Command: /prescan-memory for quick triage scanning

  • Build Troubleshooting – Dependency resolution for CocoaPods and Swift Package Manager conflicts

    • "I added a Swift Package but I'm getting 'No such module' errors."
    • "Build works on my Mac but fails on CI. Both have the latest Xcode."

  • Performance Profiling – Instruments decision trees for CPU, memory, battery profiling with 3 real-world examples

    • "Scrolling is slow and I need to know if it's Core Data or SwiftUI."
    • "We have a deadline and my app feels slow. What should I optimize first?"
