Swift getline

getline.swift

/**
* Unfortunately, this is the only working method I've found to get

* I shouldn't need to define this function.

// Usage: var input = getline()

func getline() -> String {
    var keyboard = NSFileHandle.fileHandleWithStandardInput()
    var inputData = keyboard.availableData
    var line = NSString(data: inputData, encoding:NSUTF8StringEncoding)
    # Remove the newline character
    return line.substringToIndex(line.length-1)
}

This can obviously be updated to specifically trim a newline character, rather than just hackily removing the last character.

That's horrible... Even C has an easier to read a newline... though it may not be any shorter.

@rcmaniac25 Swift isn't really meant to be reading from the keyboard so it's pretty understandable that C does it better...
