help please

Using the println statement, print out the value of the language element from the result tuple.

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

return (greeting, language)

}

var result = greeting("Tom")

i know its probably something really simple but i just can't seem to figure it out?

you can decompose the tuple using dot syntax like so: tupleName.tupleElementName

so since the tuple is named result and it has an element called language you would use result.language

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)

the swift eBook has a section that covers tuples here

If you are looking for the value of language you should write:

println(result.greeting)
