Currently our greeting function only returns a single value. Modify it to return both the greeting and the language as a tuple. Make sure to name each item in the tuple: greeting and language. We will print them out in the next task.
func greeting(person: String) -> String {
let language = "English"
let greeting = "Hello \(person)"
return greeting
}

71,830 PointsYou need to return a tuple. So you do this when declaring the function: -> (greeting: String, language: String) and then you return a tuple: return (greeting, language). Note that they asked you to name the members of the tuple.
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}
let result = greeting("Tom")
println(result.language)

Treehouse TeacherI would prefer to see what you've tried that's failed. That way we can help you with understanding the concept. In the definition of the function the thing after the arrow in the first line is what it's going to return. Right now, it only returns one string. And the actual return of the string is found at the bottom of the function. Here you return greeting. We need to return two strings and here's how we do that.
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}
As you can see, in the definition we say we're going to return two strings. One named greeting and one named language. Inside the function we create those variables then assign them a string. At the end of the function we return both strings, just as we said we were going to do in the definition. Hope this helps!
