I am confused on the Code Challenge! Swift 3: In this game of ours ...

var initialScore = 8

initialScore += 1

let isWinner = totalScore != 10

operators.swift 
// Enter your code below

var initialScore = 8

initialScore += 1

let isWinner = totalScore != 10

Corrected code:

var initialScore = 8
initialScore += 1
let isWinner = initialScore != 10

Explanation:

First line sets initialScore to an Int value of 8

Second line adds 1 to the intialScore. Value is now 9

Third line: the statement to the right of the = sign is returning a boolean value. It effectively asks: True/false -- initialScore does not equal 10? The result of this comparison is true because initialScore currently equals 9. isWinner is currently set to a value of "true"
