Since this thread was resurrected I thought I would try it in Swift.

import Foundation

func input() -> String {
    var keyboard = NSFileHandle.fileHandleWithStandardInput()
    var inputData = keyboard.availableData
    return NSString(data: inputData, encoding:NSUTF8StringEncoding)
}

let numbers = ["Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine"]
	
println("Enter numbers: ")

var inputString:NSString = input()

for var index = 0; index < inputString.length; ++index {
     let asciiValue = inputString.characterAtIndex(index)
	
    if	asciiValue >= 48 && asciiValue <= 57 {
        let numberIndex = Int(asciiValue) - 48
	println("\(numbers[numberIndex])")
    }
}
