converting @Anthony's answer to Swift 3.0 worked perfectly for me:

func scrollViewDidScroll(_ scrollView: UIScrollView) {

    visibleRect.origin = yourCollectionView.contentOffset
    visibleRect.size = yourCollectionView.bounds.size
    let visiblePoint = CGPoint(x: CGFloat(visibleRect.midX), y: CGFloat(visibleRect.midY))
    let visibleIndexPath: IndexPath? = yourCollectionView.indexPathForItem(at: visiblePoint)
    print("Visible cell's index is : \(visibleIndexPath?.row)!")
}
