SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you identify and resolve performance issues in your Apple platform applications, ensuring a smooth and responsive user experience.

Core Features & Use Cases

  • Instruments Guidance: Provides step-by-step instructions for using Xcode Instruments (Time Profiler, Allocations, Leaks, Energy Log) to diagnose problems.
  • Bottleneck Identification: Helps pinpoint CPU hotspots, memory leaks, slow launches, and excessive energy consumption.
  • Use Case: Your app is stuttering during complex animations. Use this Skill to profile the UI with the Time Profiler and identify the main thread blocking operations, then apply the recommended fixes.

Quick Start

Use the performance-profiling skill to diagnose why my app is hanging.
