I think I have the code correct? Seems to not work, or what am I doing wrong?

Help :(

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

    return (greeting,language)
}

var result = greeting("Tom")

println(result.language)

this is the return statement in your function:

return (greeting,language)

that is correct. greeting needs to come first. however your return type is:

(language: String, greeting: String)

that does not match what you are returning.

you have the order of the tuple members reversed in your return type. fix it so that greeting comes first in the return type, then language

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

    return (greeting,language)
}
