Enumeration, or Enum for short, is a popular data type in many languages. It groups related values in a type-safe way within the code.

In Swift, Enumeration adopts many features supported by the first-class type, like struct, and class. It has initializers to provide an initial case value. It can be extended to expand functionality. Enum can have computed properties and instance methods to provide additional information. It also can implement protocol to align the behavior.

Enumeration is introduced with a pair of braces with the enum keyword.
