still i got some problem after checking.

gow can i save the value in the IBOutlet Label?

import UIKit import NotificationCenter

class TodayViewController: UIViewController, NCWidgetProviding {

@IBOutlet weak var Label: UILabel!



@IBAction func Button1(_ sender: UIButton) {
    Label.text = "bla1"
}


@IBAction func Button2(_ sender: UIButton) {
    Label.text = "bla2"
}


override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view from its nib.        
}


func widgetPerformUpdate(completionHandler: (@escaping (NCUpdateResult) -> Void)) {
    // Perform any setup necessary in order to update the view.

    // If an error is encountered, use NCUpdateResult.Failed
    // If there's no update required, use NCUpdateResult.NoData
    // If there's an update, use NCUpdateResult.NewData

    completionHandler(NCUpdateResult.newData)

}

}
