An enumeration is a user-defined data type which consists of set of related values. The keyword is enum .Enumeration in swift also resembles the structure of C and Objective C. Let me add a use case .

enum ClimateinState {
case Hot
case Cold
case Moderate
case Rainy
}
var season = ClimateinState.Hot
switch season {
case .Hot:
print("You are in Rajasthan")
case .Cold:
print("You are in Kashmir")
case .Moderate:
print("Climate is Odisha")
case .Rainy:
print("Climate is Mumbai")
}
Output :-
Climate is Cold
