title: UIVisualEffectView in iOS 10
body: <p>I am presenting a UIViewController that contains a UIVisualEffectView as follows:</p>
  
  <pre><code>-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
      [self performSegueWithIdentifier:@"segueBlur" sender:nil];
  }
  
  -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
      if([segue.identifier isEqualToString:@"segueBlur"]) {
          ((UIViewController *)segue.destinationViewController).providesPresentationContextTransitionStyle = YES;
          ((UIViewController *)segue.destinationViewController).definesPresentationContext = YES;
          ((UIViewController *)segue.destinationViewController).modalPresentationStyle = UIModalPresentationOverFullScreen;
      }
  }
  </code></pre>
  
  <p>As you can see, I'm using the UIModalPresentationStyleOverFullScreen so that when the view controller with blur appears, the blur will be 'applied' to the content of the view controller that is presenting it; the segue has a Cross Dissolve transition style.</p>
  
  <p>The effect looks as expected. However, in iOS 9 the presentation is smoother than in iOS 10. In iOS 10 when the view controller appears it seems like a 2-step animation, while in iOS 9 the blur is applied immediately.</p>
  
  <p>A picture is worth a thousand words so I uploaded a video showing this strange behavior:</p>

  <p>My question is: How can I present the view controller in iOS 10 as it is presented in iOS 9?</p>
