xcode 8 swift 3 UItableview space between cells?

i am trying to make space between cells in `UItableview` i've checked google all posts i found is more than 3 years old , when i try to apply them i am getting so many errors, is it possible to make space between cells in `UItableview` ? my Code : ``` func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "ImageCell") as! ImageCell cell.model = self.modelAtIndexPath(indexPath) let url = URL(string: cell.model.imageName) cell.imgBack.kf.setImage(with: url) return cell } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { //send back playlist count if (section == 0) { return self.lists_arr.count } return 0 } func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { tableView.deselectRow(at: indexPath, animated:true) } func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) { let imageCell = cell as! ImageCell self.setCellImageOffset(imageCell, indexPath: indexPath) } //number of sections in table func numberOfSections(in tableView: UITableView) -> Int { return 1 } func modelAtIndexPath(_ indexPath: IndexPath) -> CellPlaylist { return self.lists_arr[(indexPath as NSIndexPath).row % self.lists_arr.count] } func scrollViewDidScroll(_ scrollView: UIScrollView) { if (scrollView == self.tblMain) { for indexPath in self.tblMain.indexPathsForVisibleRows! { if let imgCel : ImageCell = self.tblMain.cellForRow(at: indexPath) as? ImageCell { self.setCellImageOffset(imgCel, indexPath: indexPath) } } } } func setCellImageOffset(_ cell: ImageCell, indexPath: IndexPath) { let cellFrame = self.tblMain.rectForRow(at: indexPath) let cellFrameInTable = self.tblMain.convert(cellFrame, to:self.tblMain.superview) let cellOffset = cellFrameInTable.origin.y + cellFrameInTable.size.height let tableHeight = self.tblMain.bounds.size.height + cellFrameInTable.size.height let cellOffsetFactor = cellOffset / tableHeight cell.setBackgroundOffset(cellOffsetFactor) } ``` The class of TableCell : ``` class ImageCell: UITableViewCell { @IBOutlet weak var lblTitle: UILabel! @IBOutlet weak var imgBack: UIImageView! @IBOutlet weak var imgBackTopConstraint: NSLayoutConstraint! @IBOutlet weak var imgBackBottomConstraint: NSLayoutConstraint! let imageParallaxFactor: CGFloat = 70 var imgBackTopInitial: CGFloat! var imgBackBottomInitial: CGFloat! var model: CellPlaylist! { didSet { self.updateView() } } override func awakeFromNib() { self.clipsToBounds = true self.imgBackBottomConstraint.constant -= 2 * imageParallaxFactor self.imgBackTopInitial = self.imgBackTopConstraint.constant self.imgBackBottomInitial = self.imgBackBottomConstraint.constant } func updateView() { // self.imgBack.imageFromServerURL(urlString: self.model.imageName) //self.getImage(url: self.model.imageName,imgView: self.imgBack) //self.model.imageName self.layer.cornerRadius = 10 self.layer.masksToBounds = true self.layer.cornerRadius = 8 self.layer.shadowOffset = CGSize(width: 0, height: 3) self.layer.shadowRadius = 3 self.layer.shadowOpacity = 0.3 self.layer.shadowPath = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: .allCorners, cornerRadii: CGSize(width: 8, height: 8)).cgPath self.layer.shouldRasterize = true self.layer.rasterizationScale = UIScreen.main.scale self.contentView.layoutMargins.top = 20 self.lblTitle.text = self.model.title } func setBackgroundOffset(_ offset:CGFloat) { let boundOffset = max(0, min(1, offset)) let pixelOffset = (1-boundOffset)*2*imageParallaxFactor self.imgBackTopConstraint.constant = self.imgBackTopInitial - pixelOffset self.imgBackBottomConstraint.constant = self.imgBackBottomInitial + pixelOffset } } ``` The storyboard : what i am getting : what i want :
