    let selector = #selector(self.openURL(_:))
    while responder != nil {
        if responder!.responds(to: selector) && responder != self {
            responder!.perform(selector, with: URL(string: "SecurityPPSwiftFinal://")!)

UIApplication object is not available in App Extensions.

For APIs not available in App Extensions, refer to: https://developer.apple.com/library/content/documentation/General/Conceptual/ExtensibilityPG/ExtensionOverview.html#//apple_ref/doc/uid/TP40014214-CH2-SW2

To open the App from Today Extension use:

@IBAction func btnseconbutton3(_ sender: Any)
{
    self.extensionContext?.open(URL(string: "SecurityPPSwiftFinal://")!, completionHandler: nil)
}

To handle button tap event in AppDelegate after the app is opened, use:

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool
{
    if url.scheme == "SecurityPPSwiftFinal"
    {
        //TODO: Write your code here
    }
    return true
}
