The 5 W’s of Swift Extensions

This article provides a high-level introduction to Swift extensions for newcomers, structured around the 5 W's (Who, What, When, Where, Why). It explains how extensions allow adding new functionality to existing classes, structures, or enumerations, even without access to original source code. The article covers scenarios like extending third-party frameworks, Apple's frameworks, or custom libraries, and discusses when to use extensions for reusable, clean code. It is a technical tutorial relevant to Swift and iOS development, fitting the IT/TECHNOLOGY project.
