How does this skill help with iOS memory leaks?

It provides detailed workflows for using the Xcode Memory Graph Debugger and Allocations template to identify retain cycles, abandoned memory, and common capture group errors in Swift.

Does it support SwiftUI performance optimization?

Absolutely. It covers using the SwiftUI Instruments template to profile view body evaluations and identifying causes of layout thrashing or slow rendering.

Can I use this for command-line iOS debugging?

Yes, it includes a comprehensive reference for LLDB CLI commands and xctrace for recording performance data in CI/CD pipelines.

How does it handle main thread hang diagnostics?

The skill provides a strategy for using the Time Profiler to locate synchronous I/O, lock contention, or heavy processing that blocks the main thread for over 250ms.
