Checking for integer multiples
Available from Swift 5.0
SE-0225 (apple/swift-evolution) adds an isMultiple(of:) method to integers, allowing us to check whether one number is a multiple of another in a much clearer way than using the division remainder operation, %.
For example:
let rowNumber = 4
if rowNumber.isMultiple(of: 2) {
print("Even")
} else {
print("Odd")
}
Yes, we could write the same check using if rowNumber % 2 == 0 but you have to admit that’s less clear – having isMultiple(of:) as a method means it can be listed in code completion options in Xcode, which aids discoverability.
