i am stuck

Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)

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

    return (greeting,language)
}
var result = Hello
greeting "Tom"

While you're learning Swift I would suggest working out your challenges in Playground so you can get more immediate feedback.

Your issue is right below the function. You aren't assigning result to the result of the function, you're assigning it to a variable that doesn't exist. Hello has never been declared in that block of code.

You want your result to look like ("Hello Tom", "English"). In order to do this you need to assign result to greeting and then pass the string "Tom" into greeting.
