UILongPressGestureRecognizer not recognizing .ended state

As the title reads, my problem is that my UILongPressGestureRecognizer sometimes does not run the code inside the sender.state = .ended. The .began always runs and works. I have tried to notice pattern but is to infrequent and I have not found a valid pattern or causation. I simply add my UITapGestureRecognizer UILongPressGestureRecognizer to my button:

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(normalTap(_:)))
tapGesture.numberOfTapsRequired = 1
camButton.addGestureRecognizer(tapGesture)

let longGesture = UILongPressGestureRecognizer(target: self, action: #selector(longTap(_:)))
longGesture.minimumPressDuration = 0.10
camButton.addGestureRecognizer(longGesture)

And then here is my longTap function:

    @objc func longTap(_ sender: UIGestureRecognizer) {
            if sender.state == .ended {
                if movieOutput.recordedDuration.seconds == lastRecordDuration || movieOutput.recordedDuration.seconds <= 0.35 {
                    capturePhoto()
                    } else {
                    stopRecording()
                }
           } else if sender.state == .began {
            startCapture()
        }
    }

I use the longPress for video and photos, and the TapGesture for photos only. Im using AVFoundation.

I know this is old question, but writing for those who are facing issue like me.

You can get sender.state == .possible when tap is ended.

After receiving assistance from @rmaddy, the solution is basically to implement a .cancelled state action. For some reason the continuous gesture of UILongPressGesture got cancelled. In my code I implemented a `if sender.state == .cancelled.
