Hi I'm doing these quiq challenges for IOS course and I'm stuck in one of these equations and I don't know what I miss

Hi I'm doing these quiq challenges for IOS course and I'm stuck in one of these equations and I don't know what I missing

The Quistion

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?"

My Answer

let name = "Khaled" let greeting = "("Hi there,") (name)" let finalGreeting = "(greeting). ("How are you?")"

Note : I ran this code on playground and it works well !

strings.swift 
// Enter your code below
let name = "Khaled"
let greeting = "\("Hi there,") \(name)"
let finalGreeting = "\(greeting). \("How are you?")"

It works well because there is no mistake, just you don't have to put in brackets ("Hi there,") because it is not a constant or a variable si just a string.

Just change this constant this way 

// Your code 
let greeting = "\("Hi there,") \(name)"

// Change with this 

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

Next let have a look at our task, "Declare a constant named finalGreeting, and concatenate the value of greeting with the string literal " How are you?"."

// 1. Declare constant (witch you have done well)
// 2.  concatenate the value (Be careful here) greeting with the string literal " How are you?"."
// NOTE: to concatenate a variable/constant with the string literal you just use + sign
let finalGreeting = greeting + " How are you?"

So again, in the playground works well because there is not mistake as syntax but you didn't respect all the tasks for the challenge that's why
