Can this skill help find memory leaks in SwiftUI?

Yes, it provides specific workflows for using the Memory Graph Debugger and identifying common retain cycle patterns in closures, delegates, and timers.

Does it support modern Swift concurrency debugging?

Absolutely. It includes guidance for diagnosing main thread hangs caused by synchronous I/O or lock contention in modern Swift 6.3 environments.

Can I use this for automated performance tracking?

Yes, it covers the use of the xctrace CLI, which allows you to record and export profiling data in CI/CD pipelines for automated analysis.

How does it help with build failures?

The skill provides triage steps for compiler diagnostics, linker errors (like undefined symbols), and Swift Package Manager (SPM) dependency resolution conflicts.

Diagnoses and resolves crashes, memory leaks, and performance bottlenecks using advanced LLDB commands and Apple's profiling instruments.

This skill provides specialized technical guidance for debugging modern iOS applications built with Swift 6.3 and SwiftUI. It empowers developers to master LLDB for runtime state inspection, utilize the Memory Graph Debugger to eliminate retain cycles, and leverage Apple's Instruments suite to profile CPU, energy, and network usage. By covering everything from main thread hang diagnostics to Swift Package Manager triage, this skill ensures your iOS apps are performant, stable, and follow Apple's most recent best practices for system-level debugging.
