@IBAction func numbers(_ sender: UIButton) {
if let number = sender.currentTitle {
if number == “C” {
resultLabel.text = “0”
numberOnScreen = 0
} else {
if resultLabel.text == “0” {
resultLabel.text = number
} else {
resultLabel.text = resultLabel.text! + number
}
numberOnScreen = Double(resultLabel.text!)!
}
}
}
}
