17,790 PointsI'm getting a swift comile message to check preview for the compile errors - when I click on preview the page is blank a
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
if result == 0 { let isPerfectMultiple = true } else { let isPerfectMultiple = false }
what is the issue?
// 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
if result == 0 {
let isPerfectMultiple = true
} else {
let isPerfectMultiple = false
}

// 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
let isPerfectMultiple = value % divisor == 0

17,790 PointsOK thanks - that works. But why do I get a compile error on my code (without any error)? I don't get a compile error in xcode nor in ibm's swiftlang site

17,748 PointsI guess it's because you have two different constants both named isPerfectMultiple. If you want to use an if-else statement you can write like this:
// 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
let isPerfectMultiple: Bool
if result == 0 {
isPerfectMultiple = true
} else {
isPerfectMultiple = false
}

17,790 PointsAh cool - that is what I was overlooking.
