I am using UIPageViewController to show images full screen. Issue is the images are not showing full screen. Instead there is a gap on the bottom between the image and the page control view dots and on the top. I have a UIViewController which is added to UIPageController as a sub view / child and that ViewController has the images being showed using ImageView. I am trying to do this in swift/storyboard.
I changing the top bar and bottom bar option to "none" in storyboard, but it didn't work.

The ChildViewControllerCode:
class BoatContentViewController: UIViewController {
@IBOutlet weak var imageView: UIImageView!
@IBOutlet weak var titleLabel: UILabel!

override func viewDidLoad() {
super.viewDidLoad()
self.imageView.image = UIImage(named: self.imageFile)
self.titleLabel.text = self.titleText
// Do any additional setup after loading the view.
}
