How to make a shared gradient for UIView on adjacent UITableViewCell?

Question

Swift

Please point to a way to solve the problem.
There is a marker on the cells, added by swiping (UIView on Prototupe Cell)

How to make it so that when there are markers on adjacent cells, their gradient looks like "general"?

Answer 1

The first thing that comes to mind is to transfer to the cell from which to which color to make a gradient, and consider the colors as handles depending on the data.
Problems will appear if the cells are of dynamic height.
