UITableView custom cell disappears and appears randomly while scrolling

Good Evening

I have a UITableView with custom cells, which behaves weird and I can't find the solution. So my table points to the controller and uses it as dataSource. Here is the code to retrieve cells

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let tempCell = tableView.dequeueReusableCellWithIdentifier(armPointCellIdentifier, forIndexPath: indexPath) as! AircraftTableCell

    tempCell.hidden = false
    tempCell.UILabel_aircraftName.text = "CELL #\(indexPath.row) : \(tempCell)"

    print("\(indexPath.row): \(tempCell)")

    return tempCell;

}

When I scroll, cells appear and disapper. I never get nils in the print-out. Here is before scrolling up and down:

Before Scrolling

And here is after

After Scrolling

I tried googling, but nothing helps...

Update 1

So I tried debugging based in suggestion that the items get 0 height, or get moved under other items. But I actually have empty views for some cells. Here is sample debug output. You can see that one cell has switch and label, and the other doesn't. I hope somebody knows what to do :((

If anybody stumbles upon that issue. If your ViewController (that has TableView) inside it is a UITabBarController and you are having this issue, there is a temp work-around: Embed your ViewController inside NavigationController. This issue happens only when ViewController is embedded in TabBarController. Like on this picture.

Change it to

let tempCell = tableView.dequeueReusableCellWithIdentifier(armPointCellIdentifier) as! AircraftTableCell

Hope it works! Another solution is to set default values to your cell labels before give them the input of your array.
