Can this help with CI/CD performance testing?

Yes, the skill includes guidance on using the xctrace CLI to record and export performance data automatically within continuous integration pipelines.

Can I use this skill to fix UI lag?

Yes, it includes specific diagnostics for main thread hangs, using the Time Profiler to identify hot paths, and identifying common causes like layout thrashing or synchronous image decoding.

How does this skill help with memory leaks?

It provides structured workflows for using the Memory Graph Debugger and Leaks instrument, including how to enable Malloc Stack Logging to trace the exact allocation backtrace of leaked objects.

Does it cover LLDB commands for Swift?

Absolutely. It details the use of commands like 'v' for fast variable inspection, 'expr' for runtime state modification, and how to set conditional watchpoints on hardware registers.
