Having trouble creating a comparison and setting it equal to isWinner

let isWinner = true let 10 = !isWinner

Not sure what to do

operators2.swift 
// Enter your code below

var initialScore = 8
initialScore = initialScore + 1
let totalScore = ++initialScore

let isWinner = true
let 10 = !isWinner

You can increment initialScore and assign the new value to totalScore in one statement. You can also assign a boolean expression to isWinner:

// Enter your code below

var initialScore = 8
let totalScore = ++initialScore

let isWinner = totalScore != 10

I received an error when trying to increment the value of it more than once. This means I can only have one increment right?

If you want to increment totalScore again you need to make it a variable rather than a constant:

var totalScore = ++initialScore
