I am having trouble with a comparison operator challenge

How do I find the results for the comparison operator?

operators.swift 
// Enter your code below

var initialScore = 8
initialScore += 1
let comparisonOperation: Int = !10
let isWinner = 9

Hi Heather,

This one is a little odd at first, but here is the solution:

var initialScore = 8
initialScore += 1

let isWinner = initialScore != 10

Best way to explain it is that "isWinner" will equal the result of the initialScore comparison. The comparison will resolve to either true or false. That is, intialScore != 10 will return true or false depending on the value of initialScore. Since initialScore is 9, the return value for "isWinner" will be true (boolean).
