Hiding the tabbar and removing the space

Question

Is there a way to hide tabbar and remove that space left (around 50px) ?

I tried

self.tabBarController?.tabBar.hidden = true
self.extendedLayoutIncl

Swift 3:

extension UITabBarController {
    func setTabBarVisible(visible:Bool, duration: TimeInterval, animated:Bool) {
        if (tabBarIsVisible() == visible) { return }
        let frame = self.tabBar.frame
        let height = frame.size.height
        let offsetY = (visible ? -height : height)

        // animation
        UIViewPropertyAnimator(duration: duration, curve: .linear) {
            self.tabBar.frame.offsetBy(dx:0, dy:offsetY)
            self.view.frame = CGRect(x:0,y:0,width: self.view.frame.width, height: self.view.frame.height + offsetY)
            self.view.setNeedsDisplay()
            self.view.layoutIfNeeded()
        }.startAnimation()
    }

    func tabBarIsVisible() ->Bool {
        return self.tabBar.frame.origin.y < UIScreen.main.bounds.height
    }
}

To use (if for example self is a UITabBarController):

self.setTabBarVisible(visible: false, duration: 0.3, animated: true)

Swift 2.x:

extension UITabBarController {
    func setTabBarVisible(visible:Bool, duration: NSTimeInterval, animated:Bool) {
        if (tabBarIsVisible() == visible) { return }
        let frame = self.tabBar.frame
        let height = frame.size.height
        let offsetY = (visible ? -height : height)

        // animation
        UIView.animateWithDuration(animated ? duration : 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()
        }
    }

    func tabBarIsVisible() ->Bool {
        return self.tabBar.frame.origin.y < UIScreen.mainScreen().bounds.height
    }
}

To use:

self.tabBarController?.setTabBarVisible(visible: false, duration: 0.3, animated: true)
