I solved this bug by calling reloadData() for last section:

func expandSectionPressed(sender: UIButton) {
    let object = items[sender.tag]
    object.expanded = !object.expanded
    sender.selected = object.expanded
    var indexPaths = [NSIndexPath]()
    for i in 0..<7 {
        indexPaths.append(NSIndexPath(forRow: i, inSection: sender.tag))
    }
    if object.expanded {
        tableView.insertRowsAtIndexPaths(indexPaths, withRowAnimation: .Fade)
    } else {
        // strange crash when deleting rows from the last section //
        if sender.tag < numberOfSectionsInTableView(tableView) - 1 {
            tableView.deleteRowsAtIndexPaths(indexPaths, withRowAnimation: .Fade)
        } else {
            tableView.reloadData()
        }
    }
}
