SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers diagnose and fix performance issues in SwiftUI applications, such as slow scrolling, janky animations, and unresponsive UIs.

Core Features & Use Cases

  • Performance Profiling: Utilizes Instruments 26's SwiftUI template to identify bottlenecks.
  • Root Cause Analysis: Analyzes long view body updates and unnecessary view updates using Cause & Effect graphs.
  • Optimization Strategies: Provides patterns and solutions for common SwiftUI performance pitfalls.
  • Use Case: When your SwiftUI app's scrolling is laggy, use this Skill to pinpoint which views are updating too often or taking too long to render, and apply the recommended fixes.

Quick Start

Use the axiom-swiftui-performance skill to analyze a slow SwiftUI list by profiling with Instruments 26.

FAQPage Schema
How do I fix slow scrolling and janky animations in my SwiftUI app?▼

Profile your SwiftUI app with Instruments 26 to diagnose slow scrolling and janky animations. Use the SwiftUI template to pinpoint long view body updates and unnecessary view updates, then apply actionable optimization patterns to resolve the bottlenecks.

What is the best way to profile unnecessary view updates in SwiftUI?▼

The best way to profile unnecessary view updates in SwiftUI is to use Instruments 26 and analyze Cause & Effect graphs, which help identify long view body updates and root causes of UI performance issues.

Why does my SwiftUI UI become unresponsive during view body updates?▼

Your SwiftUI UI becomes unresponsive when view body updates take too long or trigger unnecessary view updates. Use Instruments 26's Cause & Effect graphs to analyze these update cycles and identify which views are causing the performance bottleneck.

Can I use Instruments 26 to diagnose rendering bottlenecks in SwiftUI?▼

Yes, you can use Instruments 26 to diagnose rendering bottlenecks in SwiftUI by leveraging its dedicated SwiftUI template for detailed profiling and root cause analysis of slow view updates.

What are common SwiftUI performance pitfalls and how do I resolve them?▼

Common SwiftUI performance pitfalls include excessive view body updates and unnecessary view rendering. You can resolve them by profiling with Instruments 26 to identify the bottlenecks and applying recommended optimization patterns and strategies.
