I need your help with Swiftbasic, working with operators part 2

if player score 10 that means he lose.

Declare a constant named isWinner and assign the results of a comparison operation to check whether the player has won or not. For example, if the total score is not 10, then the player has won and isWinner should equal true. (Hint: Use the NOT operator)

here is the course work

var initiaScore = 8

// adding 1 to the initialScore, i did

initialScore += 1

/*which was correct, now to declare constant names isWinner and assign the results of a comparison opreation to check if the player won */

initialScore = initialScore !=10

let isWinner = initialScore.

// im getting error for this can someone help me please..

// Enter your code below

var initialScore = 8

initialScore += 1

let isWinner = initialScore !=10
