You can give associated values to enum cases. You can do this by declaring the type of value alongside each case entry inside of brackets. Consider the following answer I gave.

enum MobilePhone {
    case iPhone(String)
    case Android(String)
    case Blackberry(String)
    case WindowsPhone(String)
}

let iPhone = MobilePhone.iPhone("6S")

You can see here I have told the enum that each case can have an associated String value. So when I set the iPhone constant with the MobilePhone.iPhone enum type I can declare the associated value of "6S" along with it. :)
