I do not know what is wrong? It says i am not using interpolation.

I am sure this is simple, I am not sure what is wrong with my code.

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

Hey there,

for the second task you have to use String concatenation instead of interpolation. I also recommend writing the period in the greeting constant and you don't have to create another constant just for the greeting and "How are you?" but your code would also be fine if you want to keep those constants.

Without the extra constants and with concatenation instead of interpolation for the finalGreeting constant it would look like this:

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

I hope that helps, good luck! :)
