UIPopoverController, Xcode 6, IOS 8 using Swift

Question

I\'m having some trouble getting a UIPopover to appear using swift. The code that is commented out works fine in Objective-C, but doesn\'t work using Swift. When I tap the + in

Answer 1

Display Popover with contentView from xib

func showPopover(sender: AnyObject) {

    let contentViewController = UINib(nibName: "ContentVC", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as ContentVC
    contentViewController.modalPresentationStyle = UIModalPresentationStyle.Popover

    var detailPopover: UIPopoverPresentationController = contentViewController.popoverPresentationController!
    detailPopover.delegate = self
    detailPopover.barButtonItem = sender as UIBarButtonItem
    detailPopover.permittedArrowDirections = UIPopoverArrowDirection.Any
    presentViewController(contentViewController,
        animated: true, completion:nil)
}

Next allows to make not full screen PopoverView on iPhone for this do not forget to inherit MainViewController: UIPopoverPresentationControllerDelegate and set delegate to PopoverView

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