Help with Challenge task 2 Greeting

need help with my code on task 2 of the greeting assignment. Now that we have an appropriate greeting for our user, let's make a bit more polite by concatenating the greeting string with a second string literal.

Declare a constant named finalGreeting, and concatenate the value of greeting with the string literal " How are you?".

Example: "Hi there, Pasan. How are you?" HERE IS MY CODE ATTACHED:

strings.swift 
// Enter your code below
let name = "William"
let greeting = "Hi there,"
let finalGreeting = "How are you"

let interpolcatedGreeting = "\(greeting)\(name)\(finalGreeting)"

let name = "William"
let greeting = "Hi there, \(name)"

let finalGreeting = "\(greeting)" + "How are you?"

Here is the correct code, if you want me to explain just tell me

Hello, you are using interpolation and it gas to be concatenation.

Here is the correct code:

let name = "Tito"
let greeting = "Hi there, \(name)”

let finalGreeting = greeting + “how are you?"

let name: String = "Eddie" let greeting = "Hi there (name)" let finalGreeting = "(greeting). How are you?"

This works in Xcode but is apparently wrong on Treehouse? 🤷🏽‍♂️ Not sure why.
