Hi Treehouse, I'm having a little trouble with this task.

Xcode turns out isWinner as true but the NOT operator doesn't work in the online editor for some reason, at least the way i tried. Where is my mistake? Thanks for helping out.

operators.swift 
var initialScore = 8

initialScore += 1

let isWinner = initialScore

isWinner != 10

Hey Daniel!

// Task 1 var initialScore = 8 initialScore += 1

//Task 2 let isWinner = initialScore != 10

Try putting you last two code lines into one line. It makes it more readable and simpler. So you are giving the constant the name isWinner and then with the assignment operator: Telling the compiler that if initialScore is not 10 the player(initialScore) has won. Your code works but it can be written in a better way.

Happy coding!
