I need code (Swift 3) for the following two buttons:  @IBAction func dividePressed(_ sender: AnyObject)@IBAction func addPressed(_ sender: AnyObject) The code needs to have: ·  Public variables of the type float called numerator, denominator and total.·  A method called \’Add\’ that returns the sum of numerator and denominator and sets the total variable.·  A method called \’Divide that returns the division of the numerator and denominator and sets the total. The \’Divide\’ method should contains a \’try/catch\’ to ensure that dividing by zero is addressed.· Use the add and divide method in the class to return results when the buttons are clicked
