SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

SwiftUI projects often struggle with performance bottlenecks, deprecated API usage, and inefficient invalidation patterns that degrade frame rates and user experience. This Skill identifies issues in both source code and Instruments traces to guide targeted optimizations.

Core Features & Use Cases

  • Review existing SwiftUI code for deprecated APIs, hot paths, and unnecessary view updates.
  • Guide improvements across three primary workflows: reviewing code, implementing new SwiftUI features, and performing instrumented trace analyses with actionable recommendations.
  • Record and analyse Instruments traces to map findings to source files and known references, enabling trace-driven optimizations.

Quick Start

Ask the Skill to run a SwiftUI performance analysis on the target app and generate a structured report.

FAQPage Schema
How do I find deprecated APIs and unnecessary view updates in SwiftUI code?

To find deprecated APIs and unnecessary view updates in SwiftUI code, you need an expert analysis that reviews source files for hot paths and inefficient invalidation patterns. This Skill produces a structured, source-linked plan mapping findings to references.

How do I analyze Instruments traces to fix SwiftUI performance bottlenecks?

You can analyze Instruments traces to fix SwiftUI performance bottlenecks by recording a trace and mapping the findings directly to your source files. This Skill performs trace analysis to identify hot paths and generate actionable optimization recommendations.

What is the best way to refactor SwiftUI code for better frame rates?

The best way to refactor SwiftUI code for better frame rates involves identifying inefficient invalidation patterns and deprecated APIs causing degraded performance. This Skill analyzes code and traces to guide targeted optimizations without editing code unless requested.

Can I use this SwiftUI expert analysis for implementing new features?

Yes, you can use this SwiftUI expert analysis for implementing new features. It guides improvements across three primary workflows: reviewing code, implementing new SwiftUI features, and performing instrumented trace analyses with actionable recommendations.

Does the SwiftUI performance review automatically edit my source files?

No, the SwiftUI performance review does not automatically edit your source files. It analyzes code and traces to produce a structured, source-linked plan and metadata, mapping findings to references without editing code unless explicitly requested.
