Why is Xcode giving me an error when writing println?

//: Playground - noun: a place where people can play

import UIKit

var str : String = "Hello "

let modernProgrammingLanguage: String = "Swift"

var greeting: String = str + modernProgrammingLanguage //implicit type String or inferred type String

println("To build an iPhone app we need to learn ") print(modernProgrammingLanguage)

Hey David, println has been deprecated as of Swift 2.0. Just use print instead.

If you want to add a new line at the end you can pass it in as an argument to the terminator parameter.

Hope that made sense.
