How Delegation Works – A Swift Developer’s Guide

This article provides a detailed explanation of the delegation design pattern in Swift, aimed at developers new to the concept. It builds on a previous article about what delegation is, diving into how it works by introducing key players: the delegator class and the delegate class. The author explains how protocols serve as an abstraction layer, acting as blueprints or contracts that define required methods and properties. Using analogies like house construction and legal contracts, the article clarifies how protocols guarantee behavior from the delegate while imposing obligations. The content is technical, focused on iOS and Swift programming, and includes references to Swift 3.0. It is relevant to IT/TECHNOLOGY as it covers software design patterns and mobile development.
