Change tab and push to current navigation stack

[projectfebr]

Hello! Need help.
UITabBarController with two tabs: main page and catalog.

Let's say the current stack of controllers in the catalog is:
UINavigationController -> MainCatalogController -> CatalogController -> CatalogController.

While on the main tab, I need to go to the catalog tab, create a new SearchViewController and push it to the catalog navigation stack.

I didn't find anything like this in the example

@projectfebr Hi

Would love to help but I need a bit more details.

First, SearchViewController. Is it a standalone view controller or you want to present UIKits default UISearchController within CatalogController.
Second, what are the requirements for presentation? Should it be presented just latest in the UINavigationController that is in the catalog tab?

1. SearchViewController: UIViewController, my custom class, its for example.
2. The hierarchy should be like this: UITabBarController[catalog] -> UINavigationController -> MainCatalogController -> CatalogController -> CatalogController -> SearchViewController

Who is building the second step? Basically what I ask is do you already have UITabBarController[catalog] -> UINavigationController -> MainCatalogController -> CatalogController -> CatalogController built and just want to switch the tab and push SearchViewController? Or there is something more complex? Because if you just want to push and switch the tab its enough to write .from(GeneralStep.custom(using: ClassFinder<MainCatalogController, Any?>()).expectingContainer())

@projectfebr Any update?

[projectfebr]

@ekazaev sorry. I need to switch the tab, create SearchViewController and push it to the navigation stack without changing all other VCs.

This .from(GeneralStep.custom(using: ClassFinder<MainCatalogController, Any?>()).expectingContainer()) variant removes all VCs that were above MainCatalogController.
