iOS Swift 2.0 Basics Swift Operators Working With Operators: Part 2

I'm stuck. What am I missing here? I think I need to add in "let isWinner != totalscore = 10"

Not sure how to properly write this

// Enter your code below

var initialScore = 8
var totalScore = initialScore
totalScore = ++initialScore

let isWinner != 10

You are close. However, there are a few things wrong.

As always, I recommend to break down the problem and then try the solution in the Xcode playground.

The first thing they ask you to do is to create a constant called totalScore so you have to use let. Since you are using a constant, you have to increment the initialScore on the same line since you cannot change a constant later.

// Enter your code below

var initialScore = 8
let totalScore = ++initialScore // increment before assignment by using ++

For step 2, you are declaring a winner if totalScore does not equal 10. In your case, that check is missing. It would look like this.

var initialScore = 8
let totalScore = ++initialScore

let isWinner = totalScore != 10 // if totalScore is not equal to 10, you get true.  Otherwise you get false

I hope that helps,

Thank you so much, Mike! Trying to solve it in the Playground first really helped me break it down and understand it a bit better. I will definitely try your app. Thanks again!
