How to change animation direction on pushViewController on leftBarButtonItem?

I've added a leftBarButtonItem to a NavigationBar(in conjunction with NavigationController). The leftBarButtonItem is on the top ViewController.

When I use the pushViewController func to go the next ViewController, the animation is from right to left, the same as when pressing a button on the right side of the navigationBar.

How can I change the animation direction to go from left to right, same as for example in Tinder when pressing the left button on the navigation bar?

Here's the code:

let profileButton = UIBarButtonItem(image: #imageLiteral(resourceName: "profile"), style: .plain, target: self, action: #selector(self.showProfile))
    self.navigationItem.leftBarButtonItem = profileButton

@objc func showProfile() {
    let profileViewController = storyboard?.instantiateViewController(withIdentifier: "profile") as! ProfileViewController
    self.navigationController?.pushViewController(profileViewController, animated: true)
}

To animate while push to another viewController, you can use CATransition

@objc func showProfile() {
    let profileViewController = storyboard?.instantiateViewController(withIdentifier: "profile") as! ProfileViewController
    let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
    transition.type = CATransitionType.push
    transition.subtype = CATransitionSubtype.fromLeft       
    navigationController?.view.layer.add(transition, forKey: kCATransition)
    self.navigationController?.pushViewController(profileViewController, animated: true)
}

You can change the animation direction as fromRight, fromTopfromBottom

You cannot change the direction of UINavigationController. In order to achieve that, you'll have to create it on your own. If you want to implement a menu, you can check out SideMenu.
