Swift Performance Optimization

Purpose

Core Principle: Optimize Swift code by understanding language-level performance characteristics—value semantics, ARC behavior, generic specialization, and memory layout—to write fast, efficient code without premature micro-optimization.

Swift Version: Swift 6.2+ (for InlineArray, Span, @concurrent) Xcode: 16+ Platforms: iOS 18+, macOS 15+
