   Here's my suggestion :

   Start by defining your own error type like :

   enum TextFieldError: Error {
       case emptyTextField
   }
   
   extension TextFieldError: LocalizedError {
       public var errorDescription: String? {
           switch self {
           case .emptyTextField:
               return "Here, the string you want to display below the text field"
           }
       }
   }
   

   Then, you can use later it as :

   if titleTextField.text == "" {
          let error: Error = TextFieldError.emptyTextField
          titleTextField.setError(error, animated: true)
   }
   

   Hope it will help
