                                                           permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];

Swift 5

Create a class that inherits from UITabBarController and set the protocol UITabBarControllerDelegate.

class CustomTabController: UITabBarController, UITabBarControllerDelegate {

   override func viewDidLoad() {
       super.viewDidLoad()
       self.delegate = self 
   }
}

Implement the method tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool.

From there, a simple if-else statement to check what the current controller class is will suffice.

func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool {
    if viewController is YourViewController {
        self.present(YourViewController(), animated: true)
        return false
    } else {
        return true
    }
}

For this purpose
1) set the delegate of the tabbar

2) implement the method : -(void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item

3) now display popover for the specific item
