Interface Builder : cannot assign custom class to table view controller

I am trying to create a simple app for iOS that uses a tab bar controller to present either a map view or a table view. Both the map view and the table view have the same navigation bar button items:

A Logout button on the left, and Refresh, Add New buttons on the right side of the navigation bar. So I have started experimenting the idea of having a parent controller called LocationViewController, which inherits from the UIViewController.

For the table view, I have a controller called TableViewController: LocationViewController, and another controller called MapViewController: LocationViewController.

On the storyboard, I added a set of two buttons (for refresh and add new) to the top header section of each view (very small, may be hard to see). See the image attached below:

MapView

TableView

There is no problem for me to assign the custom view controller MapViewController to my map view panel, but I cannot find the custom controller class TableViewController in the panel (see the below screenshot)

custom table view controller class not found

I found a similar post on stackoverflow, and a reboot solved that problem, which I also tried, but did not solve my problem at all.

You may need to subclass it from UITableViewController. Replace the UIViewController parent class for UITableViewController, like this:

class ViewController: UITableViewController {

Then make sure you selected the View Controller where blue color is all around it and then you can place the name of the class that inherits from UITableViewController.

You have added youe buttons in the wrong place. I do not know the right name for the bar, but it contains "associated objects". What you want to achieve should look something like this : enter image description here Unfortunatelly, you cannot add two UIBarButtonItems to one side of navigation bar via interface builder. You can either drag a UIView instead of UIBarButtonItem to that "slot" and add two UIButtons there, or you ca add multiple buttons from code.

Also, it seems that the name of your question is a bit misleading :) After carefull reread of your post I found the "right" question.

Answer - you have added a UITableViewController in your storyboard, but your class doesn't inherit from UITableViewController. If you want to keep the base class, you will have to make it a "plain" UIViewController and add a UITableView to it. Note, that this way you won't be able to have prototype cells.
