iOS Swift Functions and Optionals Functions Function Return Types

return function

Modify the definition of the function named greeting to return a String and replace the println statement with a return statement. The function should return a greeting. For example, if you pass in a string "Tom" then the return string would be: "Hello Tom".

returns.swift
func greeting(person: String) -> String {
return person
}

All you have to do is :

  func greeting(person: String) -> String {
      return   println("Hello \(person)")
             }

You don't type println. Just return("Hello (person))
