Swift delegate design pattern

This article provides a practical guide to implementing the delegate design pattern in Swift. It explains the core concepts of a delegate protocol, a delegator, and a delegate object using a relatable analogy. The tutorial includes a concrete code example for a command-line input handler, discusses Apple's use of delegates in frameworks like UIKit, and emphasizes the importance of using weak properties to avoid retain cycles.
