Swift - How to check if TableView is empty

So i'm making this ToDo-list app.
This app has local notifications, but i only want them to pop-up if the tableview is empty. To keep it short : How do i check if the tableview is empty?

This is my current code :

import UIKit

class FirstViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

@IBOutlet var tblTasks : UITableView!
@IBOutlet weak var countLbl: UILabel!
var localNotification = UILocalNotification()

//For persisting data
let defaults = NSUserDefaults.standardUserDefaults()

override func viewDidLoad() {

// localNotification.alertAction = "Je hebt nog taken die gedaan moeten worden!"
localNotification.alertBody = "Je hebt nog taken die gedaan moeten worden! Namelijk nog \(updateCount)"
localNotification.timeZone = NSTimeZone.localTimeZone()

localNotification.fireDate = NSDate(timeIntervalSinceNow: 10)


override func viewWillAppear(animated: Bool) {

override func didReceiveMemoryWarning() {
// Dispose of any resources that can be recreated.

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
return taskMgr.tasks.count


//Define how our cells look - 2 lines a heading and a subtitle
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "Default Tasks")

//Assign the contents of our var "items" to the textLabel of each cell
cell.textLabel!.text = taskMgr.tasks[indexPath.row].name
cell.detailTextLabel!.text = taskMgr.tasks[indexPath.row].description
cell.backgroundColor = UIColor.clearColor()

return cell


func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath){

if (editingStyle == UITableViewCellEditingStyle.Delete){



Anyone who can help me?
Thanks ;)

You should check taskMgr.tasks.count value.
