Struct or Enum

I am tracking with what Amit is teaching about reference types verses value types. However, I am still unsure about what the advantage of a Struct is over an Enum (if any). So far I find Enums easier to use. Why should I use a Struct instead?

If you want to create a new type containing items with the same type you would use an enum, whereas structs are able to contain items of differing types, e.g.

enum Day : Int { case Monday = 1, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday }

struct Hobbit {
    var firstName: String = "Bilbo"
    var lastName: String = "Baggins"
    var age: Int = 111
    var salary: Double = "11.11"
}

Hope this helps, iain
