How Delegation Works – A Swift Developer’s Guide

This article provides a detailed explanation of how the delegation design pattern works in Swift, specifically for iOS development. It builds on a previous article that defined delegation, now focusing on the mechanics. The guide introduces the roles of a delegator class and a delegate class, and explains how protocols serve as an abstraction layer, blueprint, and contract between them. It uses analogies like house construction and legal contracts to clarify how protocols define required methods and properties without implementation, allowing multiple classes to adopt them. The content is technical and aimed at Swift developers learning design patterns.
