iOS 9 Presenting Popover takes full screen

I am trying to present a PopOver view controller, specifically to show a small filters screen next to a TextField. However it is showing as a full-screen view controller. filters_button is the one that should trigger the pop-over. Any ideas why this is showing full screen as if it were a normal ViewController? 

func showFilters(){
    let tableViewController = UITableViewController()
    tableViewController.modalPresentationStyle = UIModalPresentationStyle.Popover
    tableViewController.preferredContentSize = CGSizeMake(20, 20)

    presentViewController(tableViewController, animated: true, completion: nil)

    let popoverPresentationController = tableViewController.popoverPresentationController
    popoverPresentationController?.sourceView = filters_button
    popoverPresentationController?.sourceRect = CGRectMake(0, 0, filters_button.frame.size.width, filters_button.frame.size.height)
}

func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
    return .None
}

Note: At the top of my class I declare that it conforms the "UIPopoverPresentationControllerDelegate" protocol

You should add the following

func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle {
    return .none
}

Fixed: Given that for the PopOver to work on iPhone devices, you need to set the delegate of popoverPresentationController before the viewController is presented, that way the method below gets called by the delegate. So add 

    popoverPresentationController?.delegate = self

below 

    popoverPresentationController?.sourceRect = filters_button.frame

and move 

    self.presentViewController(filtersVC, animated: true, completion: nil)

to the end of the function.
