When I launch safari view controller(SFSafariViewController) by way of present(_:animated:completion:) method, I do not get the default modal transition behaviour, instead the transition is that of push (sliding in from the right), as if I called pushViewController:animated:

The solution was to set transition delegate to self or controller from where safari controller is being presented. Lastly adopt the UIViewControllerTransitioningDelegate with no need to implement any of the protocol methods as they are optional.

Neat solution:

let svc = SFSafariViewController(url: url)
svc.transitioningDelegate = self //neat solution to make it use default modal presentation instead of push
present(svc, animated: true, completion: nil)

Remember again, we need to adopt the UIViewControllerTransitioningDelegate protocol in our view controller, but there are no required functions to implement.
