You can try this control. Its is pretty neat. DZNEmptyDataSet

Or if I were you all I would do is

• Check to see if your data array is empty
• If it is empty then add one object called @"No Data" to it
• Display that string in cell.textLabel.text

I hope it server your purpose...... In your UITableViewController .

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if searchController.isActive && searchController.searchBar.text != "" {
        if filteredContacts.count > 0 {
            self.tableView.backgroundView = .none;
            return filteredContacts.count
        } else {
            Helper.EmptyMessage(message: ConstantMap.NO_CONTACT_FOUND, viewController: self)
            return 0
        }
    } else {
        if contacts.count > 0 {
            self.tableView.backgroundView = .none;
            return contacts.count
        } else {
            Helper.EmptyMessage(message: ConstantMap.NO_CONTACT_FOUND, viewController: self)
            return 0
        }
    }
}

Helper Class with function :

 /* Description: This function generate alert dialog for empty message by passing message and
           associated viewcontroller for that function
           - Parameters:
            - message: message that require for  empty alert message
            - viewController: selected viewcontroller at that time
         */
        static func EmptyMessage(message:String, viewController:UITableViewController) {
            let messageLabel = UILabel(frame: CGRect(x: 0, y: 0, width: viewController.view.bounds.size.width, height: viewController.view.bounds.size.height))
            messageLabel.text = message
            let bubbleColor = UIColor(red: CGFloat(57)/255, green: CGFloat(81)/255, blue: CGFloat(104)/255, alpha :1)

            messageLabel.textColor = bubbleColor
            messageLabel.numberOfLines = 0;
            messageLabel.textAlignment = .center;
            messageLabel.font = UIFont(name: "TrebuchetMS", size: 18)
            messageLabel.sizeToFit()

            viewController.tableView.backgroundView = messageLabel;
            viewController.tableView.separatorStyle = .none;
        }
