Challenge Task Swift Remainders

I am stuck on challenge task for putting result into isPerfectMultiple. I tried using an if statement, but this would not compile. What is the correct syntax?

operators.swift 
// Enter your code below
let value = 200
let divisor = 5

let someOperation = 20 + 400 % 10 / 2 - 15
let anotherOperation = 52 * 27 % 200 / 2 + 5

// Task 1 - Enter your code below
let result = value % divisor



// Task 2 - Enter your code below
if result == 0 {
 let isPerfectMultiple = true}
 else{
 let isPerfectMultiple = false}

Hi! You were asked to create a constant named isPerfectMultiple and assign to it a Boolean operation that says results is equal to 0. So here is what you should have done:

let results = value % divisor
let isPerfectMultiple = results == 0

You only needed to use the equal to operator. It is easy to confuse this operator with the assignment operator we use for variables and constants. To get this right I started to repeat to myself that when it comes to math/comparison in Swift, I need to use the double equal so it can work.

Hope I could help!
