SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

SwiftUI apps can suffer from slow renders, jank, and excessive updates that degrade user experience. This guide provides a structured approach to diagnosing, profiling, and remediating performance bottlenecks in SwiftUI code.

Core Features & Use Cases

  • Code-first review for root-cause analysis, using references/code-smells.md.

  • Profiling intake and runtime evidence collection with a structured workflow.

  • Actionable remediation guidance and an audit report template.

  • Use Case: When an app stutters during scrolling or hits high CPU, run the audit to identify the cause and outline fixes.

Quick Start

Use a SwiftUI project to obtain a prioritized performance audit with concrete remediation steps.

FAQPage Schema
How do I fix SwiftUI scrolling jank and slow rendering?▼

To fix SwiftUI scrolling jank, perform a code-first review to identify root causes, then apply structured remediation guidance to stabilize frames and improve rendering speed.

What is the best way to profile excessive CPU usage in SwiftUI apps?▼

The best way to profile excessive CPU usage is to collect runtime evidence using a structured profiling workflow, identifying bottlenecks affecting rendering and frame stability.

How do I audit a SwiftUI project for performance code smells?▼

You audit a SwiftUI project for performance code smells by conducting a code-first review using references to identify problematic patterns, then generating an audit report with actionable fixes.

Does the SwiftUI performance audit workflow support projects of varying sizes and deployment targets?▼

Yes, the SwiftUI performance audit workflow supports projects of varying size and deployment targets, applying code-first reviews and structured remediation guidance across diverse configurations.

Why does my SwiftUI app hit high CPU during view updates?▼

Your SwiftUI app hits high CPU during view updates due to excessive re-renders and performance bottlenecks, which can be diagnosed through profiling intake and root-cause analysis.

What steps should I take to validate SwiftUI performance fixes?▼

To validate SwiftUI performance fixes, follow the structured validation steps provided by the audit workflow, ensuring the applied remediation guidance aligns with the profiling intake and resolves the root cause.
