Classes in Swift can call and access methods, properties, and subscripts belonging to their superclass and can provide their own overriding versions of those methods, properties, and subscripts to refine or modify their behavior. A common way to resolve this is to declare Environment [1] as a struct and then declare each case as a static property: Extensions add new functionality to an existing class, structure, enumeration, or protocol type. A compound type is a type without a name, defined in the Swift language itself. The associated type RawType is String. Extensions can add new nested types to existing classes, structures, and enumerations: extension Int {enum Kind {case negative As enum in Swift does not have index of its values (please read the post in Martin R's comment), you have to create your self some 'index' function or to map all values to an Array to have the index.
