You can use

typedef void (^ _Nullable LGAlertViewTextFieldsSetupHandler)(UITextField * _Nonnull textField, NSUInteger index);

- (nonnull instancetype)initWithTextFieldsAndTitle:(nullable NSString *)title
                                           message:(nullable NSString *)message
                                numberOfTextFields:(NSUInteger)numberOfTextFields
                            textFieldsSetupHandler:(LGAlertViewTextFieldsSetupHandler)textFieldsSetupHandler
                                      buttonTitles:(nullable NSArray<NSString *> *)buttonTitles
                                 cancelButtonTitle:(nullable NSString *)cancelButtonTitle
                            destructiveButtonTitle:(nullable NSString *)destructiveButtonTitle;
