简单UIContextMenuConfiguration导致无法同时满足约束

Question

我创建了一个简单的ContextMenu

override func collectionView(_ collectionView: UICollectionView, contextMenuConfigurationForItemAt indexPath: IndexPath, point: CGPoint) -> UIContextMenuConfiguration? {
let configuration = UIContextMenuConfiguration(identifier: nil, previewProvider: nil){ action in
let delete = UIAction(title: "Delete", image: UIImage(systemName: "trash.fill"), identifier: nil,discoverabilityTitle: nil, attributes: .destructive, handler: {action in
self.deleteItem(index: indexPath.item)
})

return UIMenu(title: "", image: nil, identifier: nil, children: [delete])
}

return configuration
}

并在控制台中引发以下警告。

2020-07-16 22:58:16.227394+0200 RunPersonalRecord[8410:2186970] [LayoutConstraints] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want. 
Try this: 
(1) look at each constraint and try to figure out which you don't expect; 
(2) find the code that added the unwanted constraint or constraints and fix it. 
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

这可能是一个苹果错误，还是有可能以某种方式修复？谢谢

根据苹果论坛的说法，这是一个系统错误。现在我们应该忽略这些警告。对最终用户没有影响。https://developer.apple.com/forums/thread/654647?page=1#621883022
