How do I pass Challenge Task 3 on Tuples?

I put in... println(result.language)

and received...

You printed "Hello Tom". It should have printed "English"

How do I print "English?"

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)

Just switch greeting and language on your return value.

return (language, greeting)

Your code is almost right, the problem is when you return the tuple with items in incorrect order. The method signature says the tuple contains two elements language and greeting in that exact order, but the return statement constructs a tuple with greeting and language.

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

    return (language, greeting) 
}

var result = greeting("Tom") 

println(result.language)

The solution is easy, just create the tuple in right order.
