How to hide empty cell tableview, which are not at the end? Swift 3

I'm just starting swift and I'm making a calendar app. Right now I'm showing a list on events if you click on a date. All questions here are about hiding cells that are at the end of a tablieview, but mine are not so eventsTableView.tableFooterView = UIView() doesn't work.

override func viewDidLoad() {
    super.viewDidLoad()
    eventsTableView.register(UITableViewCell.self, forCellReuseIdentifier: "theCell")
    self.eventsTableView.rowHeight = 80
}

func tableView(_ eventsTableView: UITableView,
               cellForRowAt indexPath: IndexPath)->UITableViewCell{


    let event = model.events[indexPath.row]

    let theItem = eventsTableView.dequeueReusableCell(
        withIdentifier: "theCell",for: indexPath)

    let what = event.value(forKeyPath:"what") as? String
    let location = event.value(forKeyPath:"location") as? String
    let when = event.value(forKeyPath:"when") as? Date

    if model.checkDay(date: when!) == model.givendate && model.checkMonth(date: when!) == model.displayedMonth {
        theItem.textLabel?.numberOfLines = 3
        let labelText = what! + "\n" + "time: " + model.getTime(date: when!) + "\n" + "location: " + location!
        theItem.textLabel?.text = labelText
    } else {
        theItem.textLabel?.numberOfLines = 0
    }
    print(theItem)
    return theItem
}

This is what my output looks like
