UIDocumentPickerViewController - How to set the navigation bar color

Question

I want to set the navigation bar background color of my DocumentPicker to be the same as the rest of my application.

Answer 1

This will change the color of the text like "Cancel".

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

and this will change the arrow back color.

UIButton.appearance().tintColor = UIColor.blue

Don't forget to set it back to your original colors after closing the picker if it required.
