how to retrieve all visible table section header views

Question

is there a way to get all the section header views that are visible?

something similar to UITableView\'s visibleCells instance method..

Answer 1

A quick look at the UITableView documentation gives us the indexPathsForVisibleRows and combining it with map gives us the array we need:

tableView.indexPathsForVisibleRows.map{ tableView.headerView(forSection: $0.section) }

map returns the array of our visible headers-in-section.
