Pull to refresh throwing this error

Question

I'm trying to implement pull to refresh in my cloud kit note app but I am getting the following error when I pull down to run refresh:

I have enabled Refresh in storyboard of UITableview

Implemented the following in ViewDidLoad()

 self.refreshControl?.addTarget(self, action: "HandleRefresh:", forControlEvents: UIControlEvents.ValueChanged)

This is my refresh method:

    func handleRefresh(refreshControl: UIRefreshControl) {


    self.tableView.reloadData()
    refreshControl.endRefreshing()
}

It's worth nothing that the line self.tableView.reloadData() works elsewhere in my code.

Might also be worth nothing that when error occurs Xcode ends up in my AppDelegate class at this line

class AppDelegate: UIResponder, UIApplicationDelegate, UISplitViewControllerDelegate {

Answer 1

Issue solved by commenter

HandleRefresh vs handleRefresh spelling error between method and call.

Answer 2

This fixed mine :

refreshControl.addTarget(self, action:
        #selector(ViewController.HandleRefresh(sender:)),
                             for: UIControlEvents.valueChanged)
