My tab controller is not visible in UIViewController

Question

I'm new at iOS programming and I'm try to add a tab controller to a certain UIViewController. I embedded the View Controller with a tab controller using the relationship View Controller. Then I added a second view controller and added the relationship view controller to link it to the tab controller to create the second tab. However when I go to the app, the tabs are not visible. It's weird cause I feel like what I did makes sense.

Just a little mistake: your RegisterViewController should have a segue to the TabBarController, instead of directly to the MainViewController.
