Struggling to concatenate the value.

Please help.

strings.swift 
// Enter your code below
let name = "Teko."
let greeting = "Hi there, \(name)"
let finalGreeting = "\(greeting) " " How are you?"

you just need to add a plus in the last line

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

Got it, thanks. I was using Interpolation instead of Concatenation.

Hello!

There are a few ways that you can solve this problem. One way is to us the "+" symbol to connect your two strings in finalGreeting together.

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

However, you are already starting to use string interpolation when you write (greeting) within your string.

When you use the backslash and parenthesis with a variable, like "greeting" in your case, it tells the compiler that we don't literally mean to print the backslash, parenthesis, and "greeting". Rather, it tells the compiler to print the string that the variable "greeting" represents. So you would end up with:

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

Does that make sense?
