410 PointsRight result but wrong answer
I just finished doing part 2 of the exercise and it works perfect on Playground in Xcode yet the test environment won't see it as correct.
// Enter your code below
let name = "Soroush"
let finalGreeting = "How are you?"
let greeting = " Hi there, \(name). \(finalGreeting)"
//let finalGreeting = "\(greeting). How are you?"

Treehouse TeacherYou missed a word in the instructions. Declare a constant named finalGreeting, and concatenate the value of greeting with the string literal " How are you?". It explicitly says to use contatenation to add the value of greeting. You've used interpolation. And indeed, the result is the same but they're checking your ability to use both methods.
Here's the line you need:
let greeting = " Hi there, \(name). " + finalGreeting

410 PointsThank you for your response Jennifer, but this wasn't what they meant. I solved it now.
let name = "Soroush"
let greeting = "Hi there \(name)"
let finalGreeting = greeting + ". " + "How are you?
this worked for me

1,174 Pointswhat is wrong with this code?
let greeting = "Hi there," let name = "Linda"
let fullgreeting = "(greeting) (name)"
let finalGreeting = greeting + " " + name + "." + " How are you?"
