This formats the text users enter on the card donation screen. For example, "4242424242424242" becomes "4242 4242 4242 4242". It uses [the `textField(_:shouldChangeCharactersIn:replacementString:)` method of `UITextFieldDelegate`][0] to accomplish this, and implements a helper that can handle all the cases (inserting, deleting, replacing, pasting, and so on). Tested this in an iPhone 14 simulator and on a physical iOS 12 device. [0]: https://developer.apple.com/documentation/uikit/uitextfielddelegate/1619599-textfield |
