}
func testingFunc() {

Answer 1

You have created a custom UITableView subclass called TableView
This is the line of code that does this class TableView: UITableView
However, in your ViewController you are creating a generic UITableView
private var tableView: UITableView
This should be changed to
private var tableView: TableView which is the name of the custom UITableView class you created.
After this, tableView.testingFunc() should work.
