Adaptive segue in storyboard Xcode 6. Is push deprecated?

Xcode 6 interface builder by default has new checkbox "use size classes". It makes views adaptive. enter image description here

When I try to make segue between 2 views in my storyboard I have new options: enter image description here

instead old:

enter image description here

Now we have "show" and "present modally" instead of "push" and "modal". The old options are marked as deprecated. I've chosen "show" option, because in segue settings it called "show (e.g. push)

enter image description here

But it doesn't make push. Segue animation looks like slide from the bottom (modal) and navigation bar disappears.

Question is: How can I make "show" work like push? Is it possible or should I use "push (deprecated)" instead? Where can I find any information about new types of segue? The only thing that I've found in iOS8 developer library is Storyboards Help You Design Your User Interface but there is no information about "show" segue.

UPDATE

I tried to create new project and "show" is really works like "push". I think the issue in my project can be because I reuse navigation controller with code like this, but I don't know how to fix it.

if ( [segue isKindOfClass: [SWRevealViewControllerSegue class]] ) {
    SWRevealViewControllerSegue *swSegue = (SWRevealViewControllerSegue*) segue;
    
    swSegue.performBlock = ^(SWRevealViewControllerSegue* rvc_segue, UIViewController* svc, UIViewController* dvc) {
        
        UINavigationController* navController = (UINavigationController*)self.revealViewController.frontViewController;
        [navController setViewControllers: @[dvc] animated: NO ];
        [self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];
    };
    
}

After that I try to push NewViewController after MainViewController enter image description here

UPDATE 2:

I seems to be only iOS 7, iOS 7.1 issue.

Yes, use ‘Show’ instead of ‘Push’

How can I make "show" work like push? Is it possible or should I use "push (depricated)" instead?

It should; it does for me. I am using Xcode 6 beta 2 and to test I used the single view template (calling the pre made view controller in IB ‘VC_A’). I then added another view controller (‘VC_B’). I then added a button on VC_A to show VC_B and another from VC_B back to VC_A. When I add a navigation controller as the initial view controller in the storyboard and make VC_A the rootViewController, both ‘push’ and ‘show’ have the same effect. If I don’t have an initial navigation controller and I use ‘show’ I get what you described in that the VC_B does a slide up from bottom. If I try to ‘push’ I get a crash since in order to do push I must have navigation controller. So it would seem that ‘show’ will do a push in the case where a navigation controller is provided and do a present with a modal transition style if a navigation controller is not present.

Where can I find any information about new types of segue?

So I found some information in the ‘What’s New in Interface Builder’ session here. If you look at the slides you will see one slide (41) mention the change. When watching that session video you can skip to minute 38:00 where they start talking about adaptive segues. They do explain that the ‘show’ adaptive segue, for example, takes the context in account when deciding how to do the presentation of a new view controller.
