Hey Dhari,

The code challenge is asking you to "Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)". To do this, you must first declare a variable named result (like you did), and then pass the string "Tom" as a parameter when you call the greeting function, like so:

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

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

Hope this helps, Rodrigo
