2,108 PointsHow to make isWinner = True
How do I get to my answer?
// Enter your code below
var initialScore = 8
initialScore += 1
var isWinner = 10
let isWinner = true
let isWinner = !isWinner

28,558 PointsisWinner should only equal true if the initialScore is not equal to 10. Let me rephrase the challenge a bit, say you had an if statement and were asked to write a condition that would make it run only if initialScore was equal to 10 how would that condition look?
Well it would look like this initialScore == 10 and here is the thing, comparisons like that can't just be used in if statements and the like, you can assign the result of those comparisons (which is a boolean) directly to a variable like this:
let isWinner = initialScore == 10
That code will result in isWinner being true if initial score equals 10 and false otherwise.
You can negate (reverse) the result of that comparison either by using the ! operator like this:
let isWinner = !(initialScore == 10)
Or by using the not equal to != operator like this:
let isWinner = initialScore != 10
Both of those examples will result in isWinner being true only if the initialScore is not equal to 10. Which is what the task is looking for.

iOS Development Techdegree Student 2,979 PointsThe value of isWinner should be a comparison operator that checks to make sure initialScore is not equal to 10. You'll be using
!=Make sure you only declare isWinner once. Right now you've declared it three times.
Are you typing your code in Xcode first? Writing in a playground really is helpful for catching a lot of mistakes that you may overlook if you're trying to write code directly in the browser.
