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

Currently our greeting function only returns a single value. Modify it to return both the greeting and the language as a tuple. Make sure to name each item in the tuple: greeting and language. We will print them out in the next task

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

    return greeting
}

Hi Aditya. It seems that you have an incomplete question there. I presume you were unable to proceed with the challenge

The challenge is asking you to return a tuple of the two variables inside the definition of the function. To do so, you have to modify the return type in the function to the tuple to a type of (String, String), the same types as the two return values in the tuple (greeting is a String and language is also a String)

To make a tuple, you simply have to return a tuple of greeting and language variable like this: (greeting, language)

The full problem statement from viewing the challenge says: "Currently our greeting function only returns a single value. Modify it to return both the greeting and the language as a tuple. Make sure to name each item in the tuple: greeting and language. We will print them out in the next task."

That means the return type needs to look like this: (greeting: String, language: String)

This program should pass the challenge: 

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

    return (greeting, language)
}

Let me know if you have further doubts. Good luck with Swift!
