Swift 3 Navigation Bar Item Scrolling

Is it possible to have the items in a navigation bar be scrollable? In order words, if I have 5+ items in the navigation bar, I want to be able to scroll through them horizontally. I have seen it with custom buttons and custom navigation bars, but I want to know if it can be done with View Controller with an embedded Navigation Controller.

Default Show Left Bar Button Item

I am using a show segue from a Table View cell to a "Detail View" because I am using a navigation controller, the Detail View comes by default with a left bar button to take me back to Table View. Because it is done by default, I cannot figure out how to access it, to change its propertys. More specifically it's color. I am using Swift in the most current Xcode. How do you access the default navigation bar button when using a show segue?

How can I stop or fix Wakanda menu highlighting?

Wakanda's Menu Bar widget seems to not have a sense of hierarchy; that is, clicking an item will highlight it and will not un-highlight a clicked item of a different menu item group. Example below:
"Home" was clicked, and then the submenu item "View Requests" was clicked. "Home" remains highlighted, but it really should have un-highlighted.
It looks sloppy. Do you have any advice for making it nicer?
event.preventDefault() on the onClick event did not prevent the coloring change for the down state.
Edit: This is all one complex menu bar widget. It has menu bar widgets as submenu items. That's what I mean by a lack of sense of heirarchy. Wakanda fails to see the tree of menu bar widgets as ONE menu bar.
In the properties tab of the Menu Bar widget, change the value of "Show submenus" from 'On Mouse Over' (default) to 'On Mouse Click'.

Why is the bar button item only visible when selected and very dull?

I have added a bar button item in my app and it is only visible on the storyboard when it is selected , it is not visible at all when I run it on the simulator or real device, any ideas of how I could solve this? thanks !
The problem is that you are already in a UINavigationController interface. Thus, adding your own navigation bar to this view controller won't work; it is hidden behind the navigation controller's navigation bar. What you want to do is modify the navigation controller's navigation bar. You do that by adding a navigation item to this view controller, not a navigation bar.

How can you keep a new view from covering the tab bar after a segue?

I have a tab bar with 2 tabs. I ctrl-dragged from a button in the first view and released it on the second view and chose "show". The storyboard shows the tab bar on all the scenes, but when I test the button in the simulator, although it does segue to the second view, the second view doesn't show the tab bar.
How can you keep a new view from covering the tab bar after a segue?
Maybe I need to ctrl-drag somewhere else or do this programmatically?
Here is a screenshot of my story board.
When I segue to the "Read Article" view controller I would like to still see the tab bar and star icon at the bottom.
p.s. This may have been answered before with Objective-C, but I am looking for a Swift answer. Thanks.
