Xcode says my code is correct, but Teamtree says it is not?

Please help, with my code below. Teamtree won't let me move to the next part, however Xcode reads my code correctly??

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

You have forgotten the "\" backslash in the string interpolation. 

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

For the second task you are supposed to use concatenation, not string interpolation. 

let finalGreeting = greeting + " How are you?"

I did use 'backslash' but for some reason it didn't show up when I copied and pasted it here. However, I don't know how to use concatenation, so I will deffo use the example you have given above. Thank you for your help!
