Hi Jacob,

There's three tasks here. The first asks you to amend the return type to a tuple etc. You've mainly got that sorted, I think. Your code should look like this - you need to be careful to maintain the correct order of greeting then language: 

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

    return (greeting, language)
}

Next, you need to add the returned value to a variable named result:

var result = greeting("Tom")

Lastly, you need to print out one element of the tuple. That look like:

println(result.language)

I hope that makes sense.

Steve.
