This is a comprehensive router for diagnosing any performance issue in iOS apps. It covers the full spectrum: memory leaks and retain cycles, CPU profiling with Instruments or xctrace, app launch optimization, battery drain, hang diagnostics, and Swift-specific performance patterns. The decision tree is genuinely helpful because performance problems often look alike at first glance. If your app feels slow, this gets you to the right sub-skill fast, whether that's Time Profiler for general lag, hang-diagnostics for UI freezes, or app-launch for cold start regression. It also routes to automated agents for proactive scans (memory-auditor, energy-auditor) and includes practical escape hatches like timer crash patterns and LLDB debugging when profiling alone isn't enough.
