I too could not figure out the final code challenge

You need to assign a boolean value to "isWinner". We use the comparison

initialScore != 10

to determine if the score is equal to 10 or not. Then, that boolean value gets assigned to isWinner like so:

let isWinner = initialScore != 10

The answer on the other post is correct.

An alternative solution:

let initialScore = 0 iniitalScore += 1 let isWinner = !(initial Score = 10)

So, the final line will negate whatever initial Score = 10 is. If initial Score = 10 is true, then winner=false. If initial Score = 10 is false, then winner=true!

This isn't connected to any specific code challenge (instead, a video), so I can't really say whether or not this'll pass the challenge you're working on, but your code will not compile in Swift. Swift is different from its C-family predecessors in that it doesn't treat booleans as integers where 0 is false and everything else is true. A Swift Bool is its own distinct type that can't be converted directly to an Int and vice-versa using any operators, like the boolean inversion operator (!). While writing something like !10 is perfectly valid in Objective-C, it doesn't work in Swift. Based on what you've pasted in from the question, I'm guessing that the challenge wants you to check if a variable *is not equal to 10, which is a different operator. You can check if a value is not equal to another value with the not-equal comparison operator (!=), like this:

let someValue = 8

let first = someValue != 20 // first is true
let second = someValue != 8 // second is false

^^^ Yes that challenge

// Enter your code below

var initialScore = 8 initialScore += 1

let isWinner = !(initialScore==10)
