define enum swift

Struct : Value Type | No Inheritance | No Deinitializers | No Type casting
Class : Reference Type | Inheritance supported | Has Deinitializers | Type casting

Common factors between struct and class:
Both allows to define properties to store values
Both allows to define methods
Both allows to define subscripts 
Both allows to define initializers
Both allows extension and protocols
