How to add optional elements in tableViewCell

You should implement optional delegate func

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat

Then you have 2 options:

- use a xib and have all elements present in the xib, hidden or visible depending on cell

In heightForRowAt, evaluate what is the required height, depending on visible items.

To adjust layout, you could create IBOutlets for the constraints at stake and adapt their value in cellForRow

- build the cell completely in code

then you have also to create the constraints

and you can compute the required height

I prefer first approach.
