Introduction
I have used Swift for windows 1.9 for debugging purpose. But you can use any Swift programming language compiler as per your availability.
func sumoftwonumbers(num1: Int, num2: Int) -> Int { if num1 == num2 { return (num1 + num2) * 3 } else { return num1 + num2 } } print(sumoftwonumbers(num1: 15, num2: 20)) print(sumoftwonumbers(num1: 30, num2: 20)) print(sumoftwonumbers(num1: 40, num2: 50))
