code:

func open() {
        UINavigationBar.appearance().barTintColor = .green
        let documentsController = UIDocumentPickerViewController(documentTypes: makeDocumentTypesList(), in: .import)
        documentsController.delegate = self
        viewControllerProvider.getViewController().present(documentsController, animated: true, completion: nil)
    }

You can just reset the appearance for UIDocumentPickerViewController only by putting this code somewhere in your application:didFinishLaunchingWithOptions: function and the bar buttons will return to their original blue or you can set any other color of your choice. The bar color, on the other hand is not customizable.

if #available(iOS 11.0, *) {
    UINavigationBar.appearance(whenContainedInInstancesOf: [UIDocumentBrowserViewController.self]).tintColor = nil
}

Use setTitleTextAttributes

UIBarButtonItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName:UIColor.white], for: .normal)

This is the only solution I found:

    UINavigationBar.appearance().tintColor = ... some color
    _viewController?.present(documentPicker, animated: true)

To my knowledge it is not possible to set the bar color only the tint color (text color). To keep the tint color for the rest of your project I reset it in the viewWillAppear of the underlying view controller.

as you ask "change color of navigation bar or text?" i haven't a solution for change navigation bar it always return nil 

self.present(documentPicker, animated: true,completion: {

                if documentPicker.navigationController?.navigationBar != nil{
                    documentPicker.navigationController?.navigationBar.barTintColor = .red
                }
            })

but if you agree to change only text

this works for me

self.present(documentPicker, animated: true,completion: {

                documentPicker.view.tintColor = .red
            })

i understand that it couldn't be the optimal but none of solutions i try work for me
