Getting error

NotificationTableViewCell.swift:64:18: Value of type 'UIViewController' has no member 'reloadData'

Answer 1

Try this (self.viewController as? YourViewControllerClass).reloadData() . UIViewController doesn't have reloadData() method - only your subclass does.

Answer 2

You need to call reload method using NSNotificationCenter

// Declare in your ViewController's ViewDidLoad

// Register to receive notification
    NotificationCenter.default.addObserver(self, selector: #selector(YourClassName. reloadData), name: Notification.Name("NotificationIdentifier"), object: nil)

In TableViewCell

@IBAction func deleteRecord(_ sender: Any) {
        // Post notification
    NotificationCenter.default.post(name: Notification.Name("NotificationIdentifier"), object: nil)
}
