Basically checking if the first visible item index == 0 is not correct, because you can hide it, My solution to this problem is to check the index if the first visible child is completely visible inside the recycler.

val isScrolledToTop = layout.findFirstCompletelyVisibleItemPosition() == indexOfChild(children.firstOrNull { it.isVisible }))

so you can combine it with a listener to enable Swipe to refresh.

binding.recyclerView.addOnScrollListener(object : OnScrollListener() {
    override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
        val isScrolledToTop = layout.findFirstCompletelyVisibleItemPosition() == indexOfChild(children.firstOrNull { it.isVisible }))
        binding.swipeToRefresh.isEnabled = isScrolledToTop
    }
}

You need to add an OnScrollListener to the RecyclerView like so, and you can enable/disable the swipeRefreshLayout using the RecyclerViews first child's visibility:

myRecyclerView.addOnScrollListener(new OnScrollListener() {
  @Override
  public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
    View firstChild = recyclerView.getChildAt(0);
    swipeRefreshLayout.setEnabled(firstChild.getVisibility() == View.VISIBLE);
  }
});
