You are trying to create a variable in a function that you want to call. This is incorrect. You want to create a new variable outside the code blocks:

//Task One
func greeting(person: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = "Hello \(person)"
    return (greeting, language)
}
//Task Two
var result = greeting("Tom")
//Look at task one func. It wants a person of type String as input. 
//So I put Tom in " " to parse a string.


//Task Three
println(result.language)
//You have already created a result variable. But task asks you to access the language part of it. 
//So you use . plus the the value you want to access.
