Is there a way to insert new items while loading more on ASCollectionNode Horizontal Scrolling

Question

I'm using ASCollectionNode horizontal scrolling and I'm trying to archive a scroll left to load more and insert items.but when I reach to the last item on the left the items are been inserted on the left instead of Right.

I implemented the insert like this..

 func addRowsIntoPhotoCollection(newPhotoCount newPhotos: Int) {
 let indexRange = (photoFeedModel.numberOfItems - newPhotos..<photoFeedModel.numberOfItems)
    let indexPaths = indexRange.map {  IndexPath(row: $0, section: 0) }
    collectionView.performBatchUpdates({
        collectionView.insertItems(at: indexPaths)
    }) { (done) in
        if self.shouldScroll == true {
              self.scrollToBeginning()
        }
    }
}

For add cells on the end of the list you have to create array of IndexPath's with rows grater then existingRows (collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int)

  [indexPaths addObject:[NSIndexPath indexPathForRow:existingRows + i inSection:0]];

swift version some like here:

var indexPaths: [IndexPath] = []

// find number of kittens in the data source and create their indexPaths
var existingRows: Int = kittenDataSource.count + 1

for i in 0..<moarKittens.count {
    indexPaths.append(IndexPath(row: existingRows + i, section: 0))
}

// add new kittens to the data source & notify table of new indexpaths
kittenDataSource.append(contentsOf: moarKittens)
if let indexPaths = indexPaths as? [IndexPath] {
    tableNode.insertRows(at: indexPaths, with: .fade)
}
