Works in Xcode, but not in the CodeChallenge

Xcode, but not in the CodeChallenge

let name = "Kjetil." let greeting = "("Hi there") (name)"

also tried different variations with the punctionation mark.

strings.swift 
// Enter your code below
let name = "Kjetil."
let greeting = "\("Hi there") \(name)"

Hi Kjetil, the reason for the error is because you're trying to use string interpolation on a value that isn't declared. 'name' is declared by the constant

let name = "Kjetil"

However 'Hi there' isn't declared and is only a part of the constant 'greeting'

There is two ways to correct this.

  1. Remove string interpolation from 'Hi there'

    let name = "Kjetil"
let greeting = "Hi there \(name)."

  2. Declare 'Hi there' as a constant

    let name = "Kjetil"
let someGreeting = "Hi there"
let greeting = "\(someGreeting) \(name)."

But for the sake of this code challenge use answer 1.
