How to make UIToolbar have a Clear Background?

Question

I have a UIToolbar that has a white tint, with a bar button item, followed by some flexible space, followed by another bar button item. I would like to make the toolbar complete

Answer 1

There is a solution in @ievgen answer in Swift 5.1

toolbar.setBackgroundImage(UIImage(), forToolbarPosition: .any, barMetrics: .default)
toolbar.backgroundColor = .clear

If you want to clear the separator gray line

toolbar.setShadowImage(UIImage(), forToolbarPosition: .any)
