Swift Performance Optimization

소개

Swift Performance Optimization provides specialized guidance for writing high-efficiency code in modern xOS development environments. It helps developers navigate complex language characteristics such as Automatic Reference Counting (ARC) overhead, Copy-on-Write (COW) behaviors, and existential container costs to eliminate runtime bottlenecks. By focusing on Swift 6.0+ features like noncopyable types and the 'some' vs 'any' distinction, this skill ensures that performance-critical algorithms and data structures are implemented with minimal overhead while maintaining type safety and code clarity.
