Amit uses print() and println() in this video.
Do these work for you?
print("Hello")
println("Hello on a new line.")

import UIKit
var str : String = "Hello "
let modernProggamingLangugage : String = "Swift"
var greeting = str + modernProggamingLangugage //implicit type String or inferred type String
print("To build an iPhone app we need to learn \ (modernProggamingLanguage)")

When you were calling your print statement to print "modernProggamingLangugage", you spelt it differently from when you created it. Also, there is should be no space between your "\" and "(" when doing string interpolation. To fix these errors your print statement should look something like this
print("To build an iPhone app we need to learn \(modernProggamingLangugage)")
Does that answer your questions? :)
