Read console input in Swift

// Function to read text input on console
// using Apple's Swift language.
// PasteBin hasn't yet support Swift
// so I choose Objective C syntax highlighter.

import Foundation

// get keyboard input
func input() -> String {
    var keyboard = NSFileHandle.fileHandleWithStandardInput()
    var inputData = keyboard.availableData
    var strData = NSString(data: inputData, encoding: NSUTF8StringEncoding)!
    return strData.stringByTrimmingCharactersInSet(NSCharacterSet.newlineCharacterSet())
}

// open the console and type some text
print("Enter some text: ")
var s = input()
println("The text is '\(s)'")
