Alternativelly as @daspianist suggested in comments

Make a subclass of like this class BaseTabBarController: UITabBarController, UITabBarControllerDelegate and put this function in the subclass's viewDidLoad

func removeTabbarItemsText() {

    var offset: CGFloat = 6.0

    if #available(iOS 11.0, *), traitCollection.horizontalSizeClass == .regular {
        offset = 0.0
    }

    if let items = tabBar.items {
        for item in items {
            item.title = ""
            item.imageInsets = UIEdgeInsets(top: offset, left: 0, bottom: -offset, right: 0)
        }
    }
}
