What problem does it solve?

This Skill helps you identify and resolve performance bottlenecks in your iOS applications, ensuring a smooth and responsive user experience.

Core Features & Use Cases

  • Tool Selection: Guides you to the correct Instruments tool (Time Profiler, Allocations, Core Data, etc.) based on symptoms.
  • Deep Workflows: Provides step-by-step guidance for using Instruments to analyze CPU usage, memory allocation, and data fetching.
  • Interpretation: Teaches you how to understand profiling results, avoid common pitfalls, and distinguish between real issues and normal behavior.
  • Use Case: Your app's UI is lagging when scrolling through a list. This Skill will guide you to use Time Profiler, identify the exact function causing the lag, and suggest the most effective fix.

Quick Start

Use the axiom-performance-profiling skill to diagnose why my app feels slow on the main thread.

FAQPage Schema
How do I fix iOS app UI lag during scrolling using Instruments?

To fix iOS app UI lag, use the Time Profiler tool in Instruments to record a session, analyze the call stack, and identify the exact function causing main thread hot spots. You can then target that specific code for optimization.

What is the best way to diagnose memory leaks in an iOS application?

The best way to diagnose memory leaks is to use the Allocations tool within Instruments. It guides you through recording memory allocation, identifying growth patterns, and distinguishing real leaks from normal app behavior.

Why does my iOS app drain battery so fast and how can I profile it?

Your iOS app drains battery fast due to excessive background activity or inefficient processing. Profile the Energy Impact using Instruments to record session data, interpret the results, and identify the exact processes causing the drain.

How do I optimize Core Data query performance for slow data fetching?

To optimize Core Data query performance, use the Core Data instrument in Instruments to record trace data. This helps analyze slow fetch requests, identify query bottlenecks, and resolve data fetching delays under pressure scenarios.

How do I interpret profiling results and avoid common pitfalls in Instruments?

Interpreting profiling results requires analyzing call stacks to distinguish between real performance issues and normal behavior. Following structured workflows helps you avoid common pitfalls by correctly identifying actual hot spots instead of system overhead.
