ios – “System gesture gate timed” out with UILongPressGestureRecognizer

I’ve a fundamental view controller (UICollectionViewController) and the cells include a UIImageView, a UILabel and a UITableView.

One thing like this

+--------------------------------------------------------------------+
|                                                                    |
| +-------------Cell-------------+  +-------------Cell-------------+ |
| |                              |  |                              | |
| | +-------+                    |  | +-------+                    | |
| | | Picture |       Label        |  | | Picture |       Label        | |
| | +-------+                    |  | +-------+                    | |
| |                              |  |                              | |
| | +--------------------------+ |  | +--------------------------+ | |
| | |                          | |  | |                          | | |
| | | TableView                | |  | | TableView                | | |
| | |                          | |  | |                          | | |
| | +--------------------------+ |  | +--------------------------+ | |
| +------------------------------+  +------------------------------+ |
:                                                                    :
+--------------------------------------------------------------------+

Within the UICollectionViewCell subclass, I add a UILongPressGestureRecognizer to the picture view:

    @IBOutlet non-public weak var imageView: UIImageView! {
        didSet {
            let gr = UILongPressGestureRecognizer(goal: self, motion: #selector(self.settingsButtonTouched))
            imageView.gestureRecognizers?.append(gr)
        }
    }

Up to now so good.
If I now faucet on the picture view, the motion will not be triggered, however solely the next textual content seems within the log:

[SystemGestureGate] <0x129f2ab10> Gesture: System gesture gate timed out.

I solely discovered references to SwiftUI, however I do not use that on this app.
Does anybody have any concept what’s inflicting this and extra importantly the best way to clear up it?
