iOS Swift Functions and Optionals Parameters and Tuples Tuples

I'm stuck! I followed the instructions and my code works in the playground.

The question is about this assignment: http://teamtreehouse.com/library/functions-and-optionals/parameters-and-tuples/tuples-2

  • I made a variable called result
  • I set the value of that variable to the output of the function
  • I passed the value "Tom" in the function

What did I do wrong?

tuples.swift 
func greeting(#person: String) -> (language: String, greeting: String) {

    let greeting = ("English","Hello \(person)")

    return greeting
}

var result = greeting(person: "Tom")

This one has got everyone at some point.. even me.

You need to add "language" after "greeting" in your tuple.

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

    return (greeting, language)
}

var result = greeting("Tom")

Thanks Aaron,

I ended up swapping the greeting and language strings, and it worked (I still returned only greeting).

Ah good to know. That worked for me too.
