Custom expandable cell from xib?

[gerchicov-bp]

It seems it works except of one thing - How to set its custom height?

It seems that it can be solved by something like this:
cell.contentView.heightAnchor.constraint(equalToConstant: 112).isActive = true
But I could solve it by inheriting and overriding table delegate methods inside ExpandableTable but the library forbids it. Could you add open or public keys where it is possible?
