Swift#3 Enumeration

• Enumeration(Enums) in swift are much more powerful than Objective C.
• Unlike Obj C, Swift enums can assign strings, characters or floats as values for each member besides integers.
• The Convenient toRaw() method returns the values assigned to each member.
• Enums can also be parameterized (give or assign values to it.)
• Swift structs can have method and are passed by value.
