In this code challenge I know that I need to make a comparison, but I don't know what comparison I need to make?

Right now all I can guess is that totalScore should not equal 10, and that if totalScore doesn't equal 10 then I can declare a winner. I don't understand how to make that distinction in the code, though.

operators2.swift 
// Enter your code below

var initialScore = 8
let totalScore = ++initialScore

totalScore != 10
let isWinner = totalScore

Ok first off, let me tell you how well you're doing. I don't think it's possible to be any closer without actually getting the answer. You did the comparison, but you never assigned the result of the comparison to anything. Then you set isWinner to totalScore which is actually a what? It's an integer and the isWinner should hold the boolean which is the result of the comparison you ran in the line just before! Take a look and see how close you are!

// Enter your code below

var initialScore = 8
let totalScore = ++initialScore
let isWinner = totalScore != 10

Oh I see! I didn't know that I could write that third line. I thought about it, and then I thought "I can't do that it's against the rules." Which was a silly thought. Thank you for the help, and for the encouraging words.
