What problem does it solve?

This Skill helps you understand language-level performance characteristics in Swift, including value semantics, ARC behavior, memory layout, and generics, to write fast, memory-efficient code without premature optimization.

Core Features & Use Cases

  • Profiler-driven decisions: Use profiling results to guide optimization focus.
  • Memory & ARC optimizations: Reduce retain/release overhead and avoid unnecessary copies.
  • Data structures & generics: Specialize generics and optimize collection usage for hot paths.
  • Code review guidance: Spot common performance anti-patterns during reviews.

Quick Start

Run Instruments to locate bottlenecks, then ask this Skill for a structured optimization plan targeting the top hotspot.
