iOS tab bar while select one tab then not select the tab aslo slide the side menu swift

Problem:

I want to create a tab bar controller with four tabs.Then after if user tabs on 4th tab then i want to open the menu also not to show the 4th tab.Instead of show the menu and previous selected as same.

Solution:

Add the delegate function

 func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool {

        if viewController is someVC {

            menushow(titleButton)

                   return false // Do not switch to the side menu as a tab bar item

               }

               return true

    }

Also add the delegate as like below

class myVC:UITabBarController,UITabBarControllerDelegate{

}

In viewdidload also set the delegate

self.delegate = self

Happy coding.....
