comparison operation

I stuck in comparison operation. Not sure what to do, Google says that I can use if statement, however it does not work still.... How to compare operations using NOT operator?

operators.swift 
// Enter your code below

var initialScore = 8
initialScore += 1

You can use the operator like this -

var initialScore = 8
initialScore += 1

let isWinner = initialScore != 10

The above line evaluates whether the initialScore is not equal to 10 and then stores the result in the isWinner constant. Since 9 is not equal to 10, hence the expression evaluates to true. Hope this helps :)
