Code is okay but when you use presentViewController, tabBarIsVisible() is not working. To keep UITabBarController always hidden use just this part:

extension UITabBarController {
    func setTabBarVisible(visible:Bool, animated:Bool) {
        let frame = self.tabBar.frame
        let height = frame.size.height
        let offsetY = (visible ? -height : height)
        UIView.animateWithDuration(animated ? 0.3 : 0.0) {
            self.tabBar.frame = CGRectOffset(frame, 0, offsetY)
            self.view.frame = CGRectMake(0, 0, self.view.frame.width, self.view.frame.height + offsetY)
            self.view.setNeedsDisplay()
            self.view.layoutIfNeeded()
        }
    }
}
