Embed multiple view controllers in a container view

Hi cesare the problem can be resolve by taking the containerView in baseClass where you can take three different viewControllers.

Please find these simple tutorial where you can add or remove the child viewController programmatically

        private func add(asChildViewController viewController: UIViewController) {
            // Add Child View Controller
            addChildViewController(viewController)

            // Add Child View as Subview
            view.addSubview(viewController.view)

            // Configure Child View
            viewController.view.frame = view.bounds
            viewController.view.autoresizingMask = [.flexibleWidth, .flexibleHeight]

            // Notify Child View Controller
            viewController.didMove(toParentViewController: self)
        }

        private func remove(asChildViewController viewController: UIViewController) {
            // Notify Child View Controller
            viewController.willMove(toParentViewController: nil)

            // Remove Child View From Superview
            viewController.view.removeFromSuperview()

            // Notify Child View Controller
            viewController.removeFromParentViewController()
        } 

For reference you can find this github project

You can only have one embed segue from a container view to another view controller. So the best way is that you can have that one view controller showing dynamic contents.

However, if you prefer to have static view controllers on storyboard, what you can do is to embed a tab bar controller to your container view. You have have all your view controllers as one of the tabs. After that, all you need to do is to first hide the tab bar, then decide which tab to show up using tabBarController.selectedIndex = yourIndex
