4,882 PointsOn the second task of the Operators Quiz for swift are we supposed to use an if statement. we have not been shown that.
this is the question: Declare a constant named isWinner and assign the results of a comparison operation to check whether the player has won or not. If the total score is not 10, then the player has won, otherwise he or she has lost. (Hint: Use the NOT operator)
var initialScore = 8
initialScore = initialScore + 1
let totalScore = ++initialScore
x != 10
let isWinner = result

25,909 PointsHey,
the task is to assign the result of a comparison to a constant named isWinner, not to write an if statement. The solution for this task should be the following:
let isWinner = totalScore != 10
Here you assign the return value of totalScore != 10 to the constant. If totalScore is not ten, the return value would be true. Otherwise it would be false.
Hope this helps :)

4,882 PointsThank you, tried that and I got this: Bummer! Make sure you increment the value of initialScore just once
Moritz Lang
25,909 PointsSorry that I didn't get this in my first answer :) You increment initialScore two times. 1. initialScore = initialScore + 1 updates initialScore and assigns the new value back to initialScore. 2. let totalScore = ++initialScore increments initialScore and assigns the value to totalScore. The second one has one crucial side effect: It increments initialScore first and then assigns it to totalScore. Because of that initialScore has also been updated. If you remove the first incrementation you should be fine.

25,909 PointsSure. Thanks in advance :)
