Pass UICollectionView touch event to its parent UITableViewCell

Question

Here is the view structure:

The outer view is a UITableView.

Inside the UITableViewCell, there is a UICollectionView

Answer 1

You can override the point(inside:with:) method of UICollectionView and manually check whether any cell contains specified point:

class CollectionView: UICollectionView {
    override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
        visibleCells.contains(where: { $0.frame.contains(point) })
    }
}
