Answer 1

Go for subclassing the QLPreviewController and use the below-mentioned code, that only works fine for me using Xcode 8.3.

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        if let firstView = self.childViewControllers.first    {
            for view in firstView.view.subviews    {
                if view.isKind(of: UIToolbar.self) {
                    view.removeFromSuperview()
                }
            }
        }
    }
