iOS Swift 2.0 Basics Swift Operators Working With Operators: Part 2

Declare a var.... Make sure its a let ?

In this code challenge I am asked to make a variable named isWinner and to assign it to the value of NOT 10

"Declare a variable 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)"

When I tried to set the isWinner var to != 10 I am greeted with this compiler error,

   " Bummer! Make sure you're using the NOT operator to make a comparison and assign the results to a constant named isWinner"

I am confused as to what to try next, or maybe I just completely overlooked my problem, can anyone help?

operators2.swift 
// Enter your code below

var initialScore = 8
let totalScore = ++initialScore

var isWinner != 10

Hey Matt,

The question ask you to assign isWinner a true or false value determined by the following statement:

"If the total score is not 10, then the player has won, otherwise he or she has lost."

With that being said, you can approach the problem like this:

var isWinner = (totalScore != 10)  // if the total score is not 10, the player has won (true)

I feel the wording is a little bland to describe this to be a true or false value, but I can see that, this is what it is asking. The code solved my problem, thank you.

Here's the answer that worked for me 

var initialScore = 8
initialScore += 1

let isWinner = (initialScore != 10)

var initialScore = 8

initialScore += 1

let totalScore = initialScore

var isWinner = (totalScore != 10)
