title: How to call initWith... in swift
body: <p>I have a an objective-c class <code>(RDAlertView)</code> which create an Alert (UIAlertView for ios &lt; 8 and UIAlertController for ios >=8 )</p>
  
  <p>Here is the code in Objective-C:</p>
  
  <pre><code>RDAlertView* alert = [[RDAlertView alloc] initWithTitle:@"Notification" 
                                                  message:@"message" 
                                               completion:completion:^(NSInteger buttonIndex, NSInteger cancelButtonIndex, NSArray *textflieds) { } 
                                        cancelButtonTitle:@"Ok" 
                                        otherButtonTitles:nil];
  
  [alert show];
  </code></pre>
  
  <p>My question is: How to call this in Swift without any change in my class (if possible)?</p>
