Try to reload data on listViewAction and use isHidden to show and hide

@IBAction func listViewAction(_ sender: Any) {
            if (a == 0){
                UIView.animate(withDuration: 0.3, animations: {
                    self.listButton.setImage(UIImage(named: "Thumbnails"), for: .normal)
                    self.tableView.delegate = self
                    self.tableView.dataSource = self
                    self.collectionView.alpha = 0.0
                    self.tableView.alpha = 1
                    self.tableView.isHidden = false
                    self.collectionView.isHidden = true
                    self.a = 1
                    self.tableView.reloadData()

                })
            }
            else{
                UIView.animate(withDuration: 0.3, animations: {
                    self.listButton.setImage(UIImage(named: "link"), for: .normal)
                    self.collectionView.alpha = 1.0
                    self.tableView.alpha = 0.0
                    self.tableView.isHidden = false
                    self.collectionView.isHidden = true
                    self.collectionView.reloadData()
                    self.a = 0
                })
            }
        }
