The comparaison is good, the problem lies with the "isWinner". You put the player's score into it, when what its need is the result of the comparaison.

Like this :

let someVariable = (comparaison process)

Thanks for your coop ....so the code should be: let isWinner = (initialScore !=10) right ?

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

That worked for me.
