Here is the Swift 3 code. Thanks a lot @Suragch for the awesome approach to create a custom AlertView.

ViewController.swift

import UIKit
class ViewController: UIViewController {

@IBAction func showAlertButtonTapped(sender: UIButton) {

        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let myAlert = storyboard.instantiateViewController(withIdentifier: "storyboardID")
        myAlert.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
        myAlert.modalTransitionStyle = UIModalTransitionStyle.crossDissolve
        self.present(myAlert, animated: true, completion: nil)

}

AlertViewController.swift

import UIKit
class AlertViewController: UIViewController {

    @IBAction func dismissButtonTapped(sender: UIButton) {
        self.dismiss(animated: true, completion: nil)
    }
}

To make it a little more interesting or to make the default effect in iOS, you could add either a VisualEffectView or change the color of the main UIView to a dark color and set its alpha to 70%. I prefer the second approach since the blur effect is not as smooth as the one with the view with 70 alpha.

Effect with VisualEffectView:
