Issue while collection view cell scroll to center in swift

I have a collection view in my VC, I scroll collection view horizontally, I want to center each cell on scroll horizontally, I have tried a code but when it scrolls it shows next cell more left then the second one .This is my code,

fileprivate let sectionInsets = UIEdgeInsets(top: 0, left: 15, bottom: 0, right: 15)

gridView.delegate = self
    gridView.dataSource = self
    gridView.register(ItemCollectionViewCell.self, forCellWithReuseIdentifier: "ItemCollectionViewCell")
    gridView.register(UINib(nibName: "ItemCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "ItemCollectionViewCell")
    gridView.showsHorizontalScrollIndicator = true
    gridView.bounces = true
    gridView.showsHorizontalScrollIndicator = false
    gridView.showsVerticalScrollIndicator = false

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
{
    return auctions?.properties?.count ?? 0
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
{
    let cell:ItemCollectionViewCell = collectionView.dequeueReusableCell(withReuseIdentifier: "ItemCollectionViewCell", for: indexPath) as! ItemCollectionViewCell;
    cell.propertyData = (auctions?.properties![indexPath.row])!
    if auctions?.status == AuctionStatus.Live.rawValue {
        cell.noOfBidsPlaced.isHidden = false
    }
    else {
        cell.noOfBidsPlaced.isHidden = true
    }
    cell.populateCell()

    return cell
}


func collectionView(_ collectionView: UICollectionView,
                    layout collectionViewLayout: UICollectionViewLayout,
                    sizeForItemAt indexPath: IndexPath) -> CGSize {
    let size = CGSize(width: 335 , height: 337)
    return size
}

//3
func collectionView(_ collectionView: UICollectionView,
                    layout collectionViewLayout: UICollectionViewLayout,
                    insetForSectionAt section: Int) -> UIEdgeInsets {
    return sectionInsets
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat
{
    return sectionInsets.left
}

func collectionView(_ collectionView: UICollectionView,
                    layout collectionViewLayout: UICollectionViewLayout,
                    minimumLineSpacingForSectionAt section: Int) -> CGFloat {
    return sectionInsets.left

}

Don't use static height and width. call this function.Maybe its helpful for you:-

// func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { // return CGSize(width: yourCollectionView.frame.size.width, height: yourCollectionView.frame.size.height ) // }
