It won't let me set a constant value so that it can be entered into an interpolated string

let name = "David" let greeting = "Hi there, " + "(name)"

strings.swift 
// Enter your code below
let name = "David"
let greeting = "Hi there,"
let interpolatedGreeting = "\(greeting) + \(name)"

Pasan Premaratne I actually tried this challenge and it looks like the correct answer isn't actually going through. 

let name = "Taylor"
let greeting = "Hi There, \(name)"
let finalGreeting = "\(greeting). How are you?"

Hi David and Taylor.

The challenge is accepting the correct answer, you are both subtly misreading the challenge.

The first part of the challenge asks for two and only two constants: name and greeting. There should not be a constant called interpolatedGreeting. greeting should contain the interpolation.

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

The second part of the challenge asks for a third constant, finalgreeting. This constant is required to be created by string concatenation NOT interpolation, which is Taylor's mistake:

let name = "taylor"
let greeting = "Hi there, \(name)"
let finalGreeting = greeting + " How are you?"

Cheers,

Alex
