Assigning the return value (a tuple) of a function to a variable.

I'm not quite sure how to do this.

tuples.swift 
func greeting(person: String) -> (language: String, greeting: String) {
    let language = "English"
    let greeting = "Hello \(person)"
    var x = (language, greeting)

    return x
}

var result = greeting("Tom")

You're almost there. Instead of returning variable x, just return the Tuple. Might also have something to do with the fact that you don't have the right placement for arguments in your function. According to the instructions it should be greeting,language.

Although your code runs fine in Xcode, Treehouse doesn't seem to like it. Below is the complete code.

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)

Hope this helps :-)
