No apriopriate scroll when changing tableFooterView's frame

This is how I change tableFooterView loaded firstly from storyboard:

enter image description here

At some time I change tableFooterView and assign a newContentSize to tableView:

self.tableView.tableFooterView?.frame.size.height = 400

var newContentSize = self.tableView.contentSize

newContentSize.height += 400
self.tableView.contentSize = newContentSize

but it is not working, because scroll ends and tableFooterView is out of scroll. Why?

let newTableFooterView = self.tableView.tableFooterView
newTableFooterView.frame.size.height = 400

self.tableView.tableFooterView = newTableFooterView

Re-assign your footer view to the table. The table will recognize it has a new footer and re-do whatever layout needs to occur for the proper size of the footer.

If we change tableFooterView's frame, the tableView is not aware of that, so its contentSize won't change properly. All it needs to be done is assign completely new tableFooterView:

let newTableFooterView = self.tableView.tableFooterView
newTableFooterView.frame.size.height = 400

self.tableView.tableFooterView = newTableFooterView
