Written on Swift.

Usage

Parent view controller

Make the parent view controller conforming to OverlayHost protocol and call showOverlay(_:) method when needed:

class ViewController: UIViewController, OverlayHost {
    @IBAction func showOverlayButtonPressed() {
        showOverlay(type: MessageViewController.self, fromStoryboardWithName: "Main")
    }
}

Overlay view controller

Make the parent view controller conforming to OverlayViewController protocol and call dismissOverlay() method when you want to dismiss the overlay:

class MessageViewController: UIViewController, OverlayViewController {
    let overlaySize: CGSize? = CGSize(width: UIScreen.main.bounds.width * 0.8, height: 120.0)
    @IBAction func closeButtonPressed() {
        dismissOverlay()
    }
}

On storyboard, set view controller's Storyboard ID to MessageViewController.
