for interpolated greeting. I have assigned constant :: let name = "Colton" and let greeting = "\(Hi there), \(name)"

or interpolated greeting. I have assigned constant :: let name = "Colton" and let greeting = "(Hi there), (name)"----The code cannot be compiled.

What is wrong?

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

I think the problem is you're treating 'Hi There' as a variable. Try: let greeting = "Hi there, \(name)" And see if it compiles.

Leamsi is correct. Interpolation is only required for the variable you are including in the string!

From the Apple Documentation:

let multiplier = 3
let message = "\(multiplier) times 2.5 is \(Double(multiplier) * 2.5)"
// message is "3 times 2.5 is 7.5"
