I have typed this same code into Xcode and it works perfectly. Please tell me what I am doing wrong.

let name = "Jason Highley" let greeting = "Hi there,"

let interpolatedGreeting = "(greeting) (name)"

strings.swift 
// Enter your code below
let name = "Jason Highley"
let greeting = "Hi there"

let interpolation = "\(greeting), \(name)"

Hi there! You're doing fine, and yes, it works in Xcode. But even functional code can fail a challenge if it doesn't meet the exact requirements. Here's a quote from the instructions:

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.

Your greeting variable is supposed to contain both the "Hi there, " and the interpolated name.

The line you're looking for is:

greeting = "Hi there, \(name)"

Hope this helps! :sparkles:

Hi there,

This code should get you where you need to be:

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

They want greeting to use string interpolation, so you need that forward slash and parenthesis around the name constant.

Then they want concatenation for the final constant, so you can use the constant value of greeting without any punctuation, then the + sign and the final piece of the String they are asking for.

I hope this helps!
