In 4.0.0, getSwiper is removed, what is the replacement?

[615349]

I have below snippet

const [swiper, updateSwiper] = useState(null);

  useEffect(() => {
    if (swiper !== null) {
      const onSlideChangeHandler = () => onSlideChange(swiper.realIndex);

      swiper.on('slideChange', onSlideChangeHandler);

      return () => {
        swiper.off('slideChange', onSlideChangeHandler);
      };
    }
  }, [onSlideChange, swiper]);

  const params = {
    initialSlide: currentIndex,
    getSwiper: s => updateSwiper(s),
    shouldSwiperUpdate: true
  };

so I have one params to get the swiper instance, and have callback on swiper slide change, but in the latest 4.0.0, getSwiper is removed.

what is the replacement? why cannot it be backward compatible?

Let use ref instead. You can find more info from README
