Check these things out
Check the view manager id if it is the same as what you mentioned in the storyboard 
Make sure your buddiesOrFacebook is not zero. Set a breakpoint on this line, and in the debug area below see if the object is null. If it is nil, then the problem is connecting the storyboard
If your current view manager does not start from the storyboard, then get the storyboard object as follows:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; UIViewController * buddiesOrFacebook = [storyboard instantiateViewControllerWithIdentifier:@"BuddiesFBFriends"] ; [self presentViewController:buddiesOrFacebook animated:YES completion:nil];
Quick update:
let storyboard = UIStoryboard(name: "MainStoryboard", bundle: nil) var buddiesOrFacebook = storyboard.instantiateViewControllerWithIdentifier("BuddiesFBFriends") self.presentViewController(myViewController, animated: true, completion: nil)
