By its dictionary definition, an enumeration (or ‘enum’ for short) is a comprehensive listing of all items in a collection. In the context of Swift, enums are a user-defined data type that comprises a fixed number of values, offering a concise yet expressive means to represent a set of related values.
While they are not without their rules, enums are flexible in that they can conform to protocols, adopt computed properties, and define initialisers to provide initial case values. We will delve into when and how it is beneficial to employ such scaffolding later in this article.
