I'm trying to perform a manual segue from a VC to a different VC which is in a TabViewController.
When I do that the tab bar it self disappears for some reason. I've tried to imbed all the TabVCs in NavigationControllers but it didn't help.
Here is the scheme of the project: 
As you can see, there is an initial navigation controller and then I try to connect the user to a tab view controller after he logs in. The segue code:
self.performSegue(withIdentifier: "AfterLogin", sender: self)
The segue works("show") but the tab bar disappears.
Thank you!
