Change colour of UIPickerView selection indicators

Question

Our UIPickerView has a dark background and the selection lines are incredibly hard to see. Is there anyway to change them to a colour of my choosing?

Update: I'm talking about the --- above and below the "Panda" item.

Answer 1

Swift 4.2

func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {

        pickerView.subviews[1].backgroundColor = UIColor.white
        pickerView.subviews[2].backgroundColor = UIColor.white

        return view
    }

This works for me!
