func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool {
UIView.setAnimationsEnabled(false)
if let nav = viewController as? UINavigationController {
if nav.viewControllers.isEmpty {
return false
}
}
return true

func tabBarController(_ tabBarController: UITabBarController, didSelect viewController: UIViewController) {
UIView.setAnimationsEnabled(true)
