What is so wrong about this?, I've entered the same exercise from here into Xcode and works just fine, except in here.

let firstValue: Int = 2 let secondValue: Int = 4

let product: Int = firstValue * secondValue

let output: String = "The product of (firstValue) time (secondValue) is (product)"

types.swift
// Enter your code below

let firstValue: Int = 2
let secondValue: Int = 4

let product: Int = firstValue * secondValue

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

The example string is "The product of 2 times 4 is 8". You are missing the s in times

It is best practice to get into the habit of using swift's type inference.

// Enter your code below

let firstValue = 2
let secondValue = 4

let product = firstValue * secondValue

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