String Interpolation in Swift not working!!

I'm not too sure why this isn't working. I'm very new to Swift so, please help.

types.swift
let firstValue = 10
let secondValue = 15
let product = firstValue * secondValue

let output = "The product of \(String(firstValue)) and \(String(secondValue)) is \(product)"

// Enter your code below

Although it does not draw an 'incorrect' response it is still unnecessary to place String before the constant. The goal is to always omit unnecessary words from your code unless it is necessary for readability. You just need to change 'and' to 'times'.

let output = "The product of \(firstValue) times \(secondValue) is \(product)"

Hey, your answer is really close, there is just one word in the output incorrect 'times', not 'and'. I dont think you need to wrap in the 'String()' either.

let firstValue = 10
let secondValue = 15
let product = firstValue * secondValue

let output = "The product of \(String(firstValue)) times \(String(secondValue)) is \(product)"
