Accessing an Enumeration association value in Swift

In this code I've written a really useless enum that defines a possible Number with Int or Float.

I can't understand how can I access the value that I set with the association. If I try to print it I get just (Enum Value)

enum Number {
    case int (Int)
    case float (Float)
}

let integer = Number.int(10)
let float = Number.float(10.5)
println("integer is \(integer)")
println("float is \(float)")

For sake of completeness, enum's association value could be accesed also using if statement with pattern matching. Here is solution for original code:

enum Number {
  case int (Int)
  case float (Float)
}

let integer = Number.int(10)
let float = Number.float(10.5)

if case let .int(i) = integer {
  print("integer is \(i)")
}
if case let .float(f) = float {
  print("float is \(f)")
}

This solution is described in detail in: https://appventure.me/2015/10/17/advanced-practical-enum-examples/

The value is associated to an instance of the enumeration. Therefore, to access it without a switch, you need to make a getter and make it available explicitly. Something like below:

enum Number {
    case int(Int)
    case float(Float)

    func get() -> NSNumber {
        switch self {
        case .int(let num):
            return num
        case .float(let num):
            return num
        }
    }
}

var vInteger = Number.int(10)
var vFloat = Number.float(10.5)

println(vInteger.get())
println(vFloat.get())

Maybe in the future something like that may be automatically created or a shorter convenience could be added to the language.
