I don't see whats wrong with my code?

let name = "mus"

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

let finalGreeting = "(greeting) How are you?"

strings.swift 
let name = "mus"

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

let finalGreeting = "\(greeting) How are you?"

Hi there! While your code would generate the same results, it does not meet the requirements of the challenge. The challenge explicitly asks you to use concatenation instead of interpolation for the last part. Concatenation is the use of the + sign to add two strings together. Interpolation is the use of the backslash and parentheses for inserting the value of a variable into a string.

Take a look at an example:

let string1 = "This is the first string."
let string2 = "This is the second string."

// concatenation
let wholeString = string1 + string2

// interpolation

let wholeString2 = "\(string1) \(string2)"

I believe the point of this challenge is to make sure you can use either method to achieve similar results. You can never have too many tools in your tool belt!

I believe you can get it with these hints, but let me know if you're still stuck! :sparkles:
