Embed Tab Bar Controller in Navigation Controller

I don’t think you’re really supposed to do this since the option is grayed out in Xcode when you select Editor -> Embed in Navigation Controller, but a hacky way to get around it is to control-drag from a free-standing Navigation Controller to the Tab Bar Controller and select “root view controller.”

Add Tab to Tab Bar Controller

Control-click from the Tab Bar Controller to the controller you want to be the new tab and select “view controllers.”
