Swift Protocol-Oriented Programming

소개

This skill enables developers to leverage Swift's unique protocol-oriented paradigm (POP) to create flexible, modular, and highly testable codebases. It provides expert guidance on defining robust protocol contracts, utilizing extensions for default implementations, and managing complex requirements through composition rather than rigid class inheritance. By mastering techniques like associated types, type erasure, and retroactive modeling, developers can build high-performance Swift applications that favor composition over inheritance and maintain strict type safety across value and reference types.
