Swift - How to present ViewController when tapping button in a custom AlertController

Question

I am developing in Swift 2.3

I have an Utils class enabling me to create UIAlertController easily.

public class Utils {

    cl

To be more Specific and use that method in any class of project. For this make a function in NSObject class. Like:

open  class func showAlert(_ delegate: UIViewController, message: String ,strtitle: String, handler:((UIAlertAction) -> Void)! = nil)
    {
        let alert = UIAlertController(title: strtitle, message: message, preferredStyle: UIAlertControllerStyle.alert)

        if handler == nil{
            alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))

        }
        else
        {
            alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: handler))
        }

        delegate.present(alert, animated: true, completion: nil)
    }

In Controller I will call the method and do the required work like:

 Alert.showAlert(self, message: "Message", strtitle: "Tittle!!", handler: {
                        (action : UIAlertAction) in
                  //Do your Work here
                })

Note: Here Alert is name of NSObject class.
