Answer 1

Subclass UIPickerViewController as below:

class CustomImagePicker: UIImagePickerController {

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        UINavigationBar.appearance().tintColor = UIColor.black
        UIBarButtonItem.appearance().setTitleTextAttributes([NSAttributedString.Key.foregroundColor : UIColor.init(red: 0.0, green: 122.0/255.0, blue: 1.0, alpha: 1.0)], for: .normal)
    }

    override func viewWillDisappear(_ animated: Bool) {

        UINavigationBar.appearance().tintColor = UIColor.white // your color
        UIBarButtonItem.appearance().setTitleTextAttributes(nil, for: .normal)
        super.viewWillDisappear(animated)

    }

}

And use As:

func openGallary()
    {
        picker!.sourceType = UIImagePickerController.SourceType.photoLibrary
        picker!.modalPresentationStyle = .currentContext
        self.present(picker!, animated: true, completion: nil)
    }

Answer 2

This is what worked for me:

    present(imagePicker, animated: true, completion: {
        imagePicker.navigationBar.topItem?.rightBarButtonItem?.tintColor = .black
    })

Answer 3

Looks like apple made some mistake with it (iOS 10, Xcode 8) because just changing tint color of UIImagePickerController could not be done, cause, before controller isn't have topItem property, or navigationController property. So have done the changes in UIImagePickerController extension. But I checked navigationController and topItem in those overrided methods: viewDidLoad, viewWillAppear, viewDidAppear. but it still was nil. So i decide to check it in viewWillLayoutSubviews, and voila! It's wasn't nil, so we can set bar tint color of exact rightBarButtomItem here!

Here is example:

    extension UIImagePickerController {
        open override func viewWillLayoutSubviews() {
            super.viewWillLayoutSubviews()
            self.navigationBar.topItem?.rightBarButtonItem?.tintColor = UIColor.black 
            self.navigationBar.topItem?.rightBarButtonItem?.isEnabled = true
        }
    }

And don't forget to call super.viewWillLayoutSubviews, it's very important ;-) EDIT: But it still has problems when return to the albums screen..
