In Objective C : Here's the code

                                             initWithTarget:self action:@selector(swipeDown:)];
swipeRecognizer.direction = UISwipeGestureRecognizerDirectionDown;
[self.view addGestureRecognizer:swipeRecognizer];

//Swipe Down Method

- (void)swipeDown:(UIGestureRecognizer *)sender{
[self dismissViewControllerAnimated:YES completion:nil];
}

I've created an easy to use extension.

Just inherent Your UIViewController with InteractiveViewController and you are done InteractiveViewController

call method showInteractive() from your controller to show as Interactive.
