Review WWDC 2018 Session 204 - Automatic Strong Passwords and Security Code AutoFill.

You will need to use a UITextField for entry and the system keyboard (no custom controls) and set the textContentType on it to .oneTimeCode (new in iOS 12).

let securityCodeTextField = UITextField()
securityCodeTextField.textContentType = .oneTimeCode

The operating system will detect verification codes from Messages automatically (messages that contain the word "code" or "passcode") with this UITextContentType set.
