I don't understand why it works in xCode but not in the browser editor.
My code when written in xCode sure seems to assign the tuple to "result", as evidenced by accessing result.0 and result.1 and getting "English" and "Hello Tom" respectively as results. Am i missing something here?
func greeting(person: String) -> (language: String, greeting: String) {
let language = "English"
let greeting = "Hello \(person)"
return (language, greeting)
}
let result = greeting("Tom")

it expects greeting to the be the first member in the tuple so change your return type/value around so that greeting is first, then language:
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}
let result = greeting("Tom")

4,446 PointsOk, I see how having them flipped could cause the checker to say "Wrong!". But I don't think the task description or the error make it clear what the problem is. After all, I DID name both items using the required names, just not in the (unspecified) order the checker was looking for.
