Hey Abdallah!

You're on the right track, but try this instead:

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!

Hi Rodrigo,

Thanks for your help, I tried it and it worked just fine :) Seems that I have to stick to the treehouse's compiler statements :)

Thanks buddy
