Swift 5

        let alert = UIAlertController(title: "Title", message: "New Message", preferredStyle: UIAlertController.Style.alert)

        let height:NSLayoutConstraint = NSLayoutConstraint(item: alert.view!, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 350)
        alert.view.addConstraint(height)


        let okAction = UIAlertAction(title: "Done", style: .default, handler: {
            (alert: UIAlertAction!) -> Void in
            // Perform Action
        })
        alert.addAction(okAction)
        let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
        alert.addAction(cancelAction)
        self.present(alert, animated: true, completion: nil)
