Hey samuel gustave,

// You need to label the components of the tuple inside your return type.

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

     // Then we modify the return statement to return these values by name
    return (greeting, language)
}

/* You then call the greeting function, by passing it a String, "Tom".
This is because it takes one argument, of type String, defined
by the function parameter. */

var result = greeting("Tom")

/* So, what happens is now result is holding the value of the function
call, greeting() on the "Tom" String. This value will be a tuple.
The first component will be greeting, the second will be language */

/* We can now access a specific component of the tuple stored
in the result variable by using dot syntax. We do this below: */

println(result.language)

Hope this helps! Good luck!
