        I have searched everywhere on how to detect screenshots, but none of the methods I have found have proved to work within my iMessage extension. I have tried one method:


        UIScreen.main.addObserver(self, forKeyPath: "captured", options: .new, context: nil)


        with the other method being:


        override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey: Any]?, context: UnsafeMutableRawPointer?) {
        if (keyPath == "captured") {
        let isCaptured = UIScreen.main.isCaptured
        //screenshot() sends a message alerting the message was screens hotted. However, the print statement didn't even run.

        I have also tried:


        let mainQueue = OperationQueue.main
        NotificationCenter.default.addObserver(forName: UIApplication.userDidTakeScreenshotNotification, object: nil, queue: mainQueue) { notification in
        // executes after screenshot


        and nothing has worked. Does anybody know how I can possibly check if a user has taken a screenshot with my iMessage extension open?
