Answer 1

You have to set modalPresentationStyle with overFullScreen value

let viewController = SearchViewController(nibName: "SearchViewController", bundle: nil)
viewController.modalPresentationStyle = .overFullScreen
present(viewController, animated: false, completion: nil)

In iOS the default color of background is black. So you navigation controller has a black background.

If you push a controller, you current controller will be replaced by your new one. If the new one have a transparent color you will see the view of your navigation.

If I understand you want your first controller to be still visible ? If yes, then you should use :

SearchViewController * searchViewController= [self.storyboard instantiateViewControllerWithIdentifier:@"SearchViewController"];
searchViewController.view.backgroundColor = [UIColor colorWithWhite:0 alpha:0.7f];
[self presentViewController:searchViewController animated:YES completion:nil];
