    You can use operator % – remainder operator

    example:

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

    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)
