iOS SLComposeViewController - url not displaying for twitter post

I am using the SLComposeViewController to post to twitter and Facebook. I have the same code for both twitter & facebook but the URL is not showing up in the twitter post. How do I fix this?

Twitter code -

socialController = [SLComposeViewController
    composeViewControllerForServiceType:SLServiceTypeTwitter];
[socialController setInitialText:@"Testing: This is the app link!"];
[socialController addImage:[UIImage imageNamed:@"image.jpg"]];
[socialController addURL:[NSURL URLWithString:@"http://www.google.com"]];
[self presentViewController:socialController animated:YES completion:nil];

Facebook code -

socialController = [SLComposeViewController
    composeViewControllerForServiceType:SLServiceTypeFacebook];
[socialController setInitialText:@"Testing: This is the app link!"];
[socialController addImage:[UIImage imageNamed:@"image.jpg"]];
[socialController addURL:[NSURL URLWithString:@"http://www.google.com"]];
[self presentViewController:socialController animated:YES completion:nil];

SLComposeViewController shows the URL as an attachment on tweet compose view. When it is sent, URL will be appended to the end of the post. You may even add multiple URLs, they will be still shown as attachments. So this is the way it should be, there is nothing to fix.
