How to get the index of visible cell in the UICollectionView

GetCurrentDisplayCell.swift

//Put this function into the extension of the UICollectionVIewDelegate and you will get the index of the current cell displaying.
// This will be helpful when you will implemenet the image slider with the help of the collectionView(by default pagination of the collectionView).    
    
    func collectionView(_ collectionView: UICollectionView, didEndDisplaying cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
        
        print("Currently visible cell is \(self.collectionView.indexPathsForVisibleItems)")
