How would I perform an action when a UITabBarItem is clicked in Swift?

Question

I would like to update my UITableView when a Tab Bar Item is clicked. (I am open to any other better suggestions of how to do this besides when the Tab Bar Item is clicked). Thanks for any help :)

Tab Bar Item

I tried to drag it over to the viewController but it only allows for an IBOutlet and Outlet Collection — Adam Strike, Jun 28 '16 at 15:42

I solved it by putting the update code in the viewDidAppear() method

Put your table view's update code in its view controller's viewWillAppear(), which should get called every time the tab is tapped.

Implement this delegate

optional func tabBarController(_ tabBarController: UITabBarController, didSelect viewController: UIViewController)

I tried using this method but it didn't work. I think it was because I didn't connect it to the actual button properly, how would I do that? – Adam Strike Jun 28 '16 at 16:56
