User Input in Swift commandline

Last Run on XCODE 11.4 / Swift 5.2

If you are writing a command line tool and need user input, the readLine() function can be used for it. It returns an optional

let input = readLine()

And, if you dont want the ending new line character, you can set the strippingNewline parameter to true.

let input = readLine(strippingNewline: true)
