An enumeration is a user-defined data type which consists of set of related values. Keyword enum is used to defined enumerated data type.
Enumeration in swift also resembles the structure of C and Objective C.
It is declared in a class and its values are accessed through the instance of that class.

{
case A

{
override func viewDidLoad() {
super.viewDidLoad()
var example2 = Example.A
example2 = .B
switch example2
{
case .A:
print("Print: A")
default:
print("Print: B")
}
// Do any additional setup after loading the view, typically from a nib.
}

super.didReceiveMemoryWarning()
