View over view breaks hierarchical

Question

I'm using MZFormSheetPresentationController to show as "pop-up" a ViewController2 (embedded in a Navigation controller as suggested) over a ViewController1.

My ViewController1 has a searchbar, a UISegmentedControl and a tableview:

When user clicks on the searchbar bookmark button, pop-up is shown.

I'd like to close the pop-up when user clicks on the done button and it works great using self.dismissViewControllerAnimated(true, completion: nil) method but I'm looking for more. I'd like to present again ViewController1 so tableView will reload data. I tried with:

self.dismissViewControllerAnimated(true, completion: nil)
        print("Dismissed")

        //goToTickets
        let next = self.storyboard?.instantiateViewControllerWithIdentifier("myTabBar") as! UITabBarController
        self.presentViewController(next, animated: true, completion: nil)

but I get this error:

Warning: Attempt to present on whose view is not in the window hierarchy!

Pop-up disappears but I can't present ViewController.

How can I do?

Thanks in advance.

Edit

This is my ViewController2 with identifier "navigationFilter"

and my tabBar:

When you are in the middle of dismissing you are trying to present next ViewController, you have to wait for completion handler and then present next view controller like this:

self.dismissViewControllerAnimated(true, completion: {
    let next = self.storyboard?.instantiateViewControllerWithIdentifier("myTabBar") as! UITabBarController
    self.presentViewController(next, animated: true, completion: nil)
})
