Is there a way for the app not to crash if the user taps on 2 or more textFields without filling them in with numbers?

Could you show the code where you crash ?
And detail the crash scenario:

Maybe you call some textField property that may be nil, like

Code Block             let text = textField!.text

If so, use optional chaining:

Code Block             if let text = textField?.text ?? ""

Or maybe you try to convert to Int something that is not
textField!.text.

Code Block let value = Int(textField!.text!)

If so replace with

Code Block let value = Int(textField!.text!) ?? 0
