When I run this code in Xcode i get no error, but I'm getting an error on here, what's wrong?

I'm very new to this, but I'm not sure exactly what's wrong.

strings.swift 
// Enter your code below

let name = "Elijah"

let greeting = "Hi there,"

let greetingName = greeting +  "\(name)"

From the question: "Second, declare a constant named greeting. Set the value of greeting to an interpolated string that combines "Hi there, " with the string stored in the name constant."

What they are asking for is a second constant that combined the literal string "Hi there, " with the string stored in the name constant. Your code would then look like this:

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

Hope this helps!

I think you're now mixing two things, String interpolation and concatenating! String values can be added together (or concatenated) with the addition operator (+) to create a new String value:

let name = "Elijah"

let greeting = "Hi there,"

let greetingName = greeting +  name

In String interpolation you're making a new string by mixing constants and literals. In this case you'd include the value of the Name -constant inside a String:

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