I can't figure out why this is failing. let finalGreeting = "\(greeting) How are you?"

I have no idea why this is not working.

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

You need to use string concatenation not interpolation, see below:

let finalGreeting = greeting + "How are you?"

How do I show my code like that from the challenge?

The reason is because you are using an "Interpolated" string instead of a "Concatenated" string for the finalGreeting. you need to make the code look like this.

let name = "Carl"

let greeting = "Hi there, (name)." //Interpolated because it is using a value from another string.

let finalGreeting = greeting + "How are you?" //Concatenated because it is adding them together (Notice the "+").

Hope this helps!

You show your code by using 3 backticks ` followed by the language you are using, the code on the line below and three backticks below the code.
