Question

I'm trying to add animation to my tabBarController when hidden. Im able to accomplish this effect with the navigationBarController by using self.navigationController?.isNavigationBarHidden = true. I'm able to hide the tabBar by using self.tabBarController?.tabBar.isHidden = true but i do not get the animation how can I do this thank you in advance.

You could change the tab bar's frame inside an animation, so something like:

func hideTabBar() {
    var frame = self.tabBarController?.tabBar.frame
    frame?.origin.y = self.view.frame.size.height + (frame?.size.height)!
    UIView.animate(withDuration: 0.5, animations: {
        self.tabBarController?.tabBar.frame = frame!
    })
}

func showTabBar() {
    var frame = self.tabBarController?.tabBar.frame
    frame?.origin.y = self.view.frame.size.height - (frame?.size.height)!
    UIView.animate(withDuration: 0.5, animations: {
        self.tabBarController?.tabBar.frame = frame!
    })
}

Which sets the tab bar just below the visible screen, so that it slides up/down from the bottom.
