I got stuck with this task. Need help!

Guys! How to assign the tuple to var result?

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

Hi SON VO,

Your code looks good so far. Do you see how the function you've defined takes a string and returns a tuple? Challenge 2 wants you to assign the result of that function (which is a tuple) to a variable called result. You probably know this already, but when you assign things to a variable, that just means setting a variable equal to something.

var something = "a great string"

Assigns the string "a great string" to the variable something.

In this case, since we want to assign the result of a function to a variable, we follow the same pattern:

var result = greeting("Tom")

Note that this line will go outside the function definition, since we're done defining it and now we want to use it.

Let me know if that helps!

Thank for your help Greg. I also got stuck with task 3: how to print out language element from the result.

Hey Son,

It sounds like you're having a lot of trouble - I would recommend watching the video again, keeping in mind the tasks you need to be able to complete.

Let us know what you've tried after watching again and giving it another shot.

Good luck!
