how should I sort out the error?

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

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

return ("greeting", "language")

}

var result = greeting(person: "Tom")

Bummer! Your 'result' has a wrong value in it.

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

    return ("greeting", "language")
}

var result = greeting(person: "Tom")

You're close, you have quotes around your constants in the return function as if it were a string.

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

    return (greeting, language) // You had quotes as if it were a string
}

var result = greeting(person: "Tom")
