Hey, instead of saying String:, you want to say person: like this:

func greeting(#person: String) {
    println("Hello \(person)")
}

greeting(person: "Jerry")

      return (greeting ,language)
      println()

Hey, this is the code I got for this challenge:

func greeting(person: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (greeting, language)
}

var result = greeting("Tom")
println(result.language)
