String Concatenate?

Now that we have an appropriate greeting for our user, let's make a bit more polite by concatenating the greeting string with a second string literal.

Declare a constant named finalGreeting, and concatenate the value of greeting with the string literal " How are you?".

Example: "Hi there, Pasan. How are you?"

---What is string Concatenate and how can i complete this challenge?

strings.swift 
let name = "Jesse"
let greeting = "hey there \(name)."

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

Jessie, this code is 100% accurate as to what the challenge is prompting. Your mistake is simple and easily fixable, instead of: 

let greeting = "hey there \(name)."

You will want: 

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

If you have any further questions, feel free to ask!

You're using concatenation correctly. However, make sure that the content of the strings matches the instructions. It should say "Hi there", not "Hey there".

I got stuck on that exercise and just completed it.

You also can't use \(greeting) because that is interpolation. Concatenation only deals with strings, not constants and variables.

The correct line for concatenation:

let finalGreeting = greeting +  "How are you?"

Hope this helps others that get stuck on this exercise in the future ! :D
