Change indexPath with indexPath.row

func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
    for cell in SliderCollectionView.visibleCells {
        let indexPath = SliderCollectionView.indexPath(for: cell)
        print(indexPath.row)

    }
}

You need if-let 

func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
    for cell in SliderCollectionView.visibleCells {
      if let row = SliderCollectionView.indexPath(for: cell)?.item {
           print(row) 
      }
    }
}

you can access the visible indices directly 

 for index in SliderCollectionView.indexPathsForVisibleItems {
    print(index.item)
 }

Try with this 

if let indexPath = collectionView.indexPath(for: cell) {
   print(indexPath.row)
}
