I need help on this code challange

Yeah, this one is a little tricky.

In the first task they are teaching you about the increment operator (++) and how it is used. If you place it before an incrementable value (like an integer) it will increment the value before it reads it, whereas if you placed it after the incremental value it will increment it after it has read it.

Consider the following code examples. This challenge task wants you to use the first example.

var initialScore = 8
let totalScore = ++initialScore

Here we are incrementing the value of initialScore to 9 before we assign it to totalScore. Then they will both equal 9.

var initialScore = 8
let totalScore = initialScore++

Here we are incrementing the value of initialScore to 9 after we assign it to totalScore. Then totalScore will be 8 (because the increment has not happened when we read it) and totalScore will be 9 (because it is incremented after we read it to set totalScore).

The second task wants you to set the value of isWinner to true unless the value of totalScore is 10.

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

So in this case as long s the value is not 10 isWinner will be true. :)
