Check if integer divided by 2. SWIFT

Question

im absolutely new to development, and trying to learn swift.

Right now i know how to make random number, and my next step is: Im trying to understand how to check if my random number (127) could be divided by 2 without decimals ? I have no idea how to do it.

Answer 1

There is a specific API isMultiple(of:) in Standard Library for this purpose

let random = Int.random(in: 0..<100)
let isEven = random.isMultiple(of: 2)

Answer 2

You can use operator % - remainder operator

example:

if randomNumber % 2 == 0 {
  print("\(randomNumber) is even")
} else {
  print("\(randomNumber) is odd")
}
