Swift 2.0 interpolatedGreeting task. Code not accepted and I can't see the issue.

What's wrong with this code below? The output on Xcode is as expected, but the compiler in the tutorial code input says the value isn't correct for an interpolated string? Any ideas?

let name = "Ash"

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

strings.swift 
// Enter your code below

let name = "Ash"

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

Hi Ash!

Thanks for asking! The person above is correct, but allow me to elaborate.

let name = "Ash"

This ^^^ is the right way to declare a constant name and assign it the string "Ash" so good job there! If you want to use name, you'll have to use string interpolation for that. Anytime you have a constant or variable that you want to output to the user, you represent it like this: \(name).

Your correct string interpolation would be:

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

Hope that helps! Keep at it!

Thanks to you too for the brilliant explanation. I'm completely new to coding so setting things straight like this is really helpful to me. Cheers!

Several problems. First, you don't include Strings within Strings. Second, the editor is picky. It said it wanted a final period. So with these changes:

let name = "Ash"

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