How to change UIScrollView Indicator color?

When I use UIColor.blue its changing, but when I try to apply RGB, its not reflected in scrollview indicator.

func scrollViewDidScroll(_ scrollView: UIScrollView) {
    let verticalIndicator: UIImageView = (scrollView.subviews[(scrollView.subviews.count - 1)] as! UIImageView)
    verticalIndicator.backgroundColor = UIColor(red: 211/255, green: 138/255, blue: 252/255, alpha: 1)
//        verticalIndicator.backgroundColor = UIColor.blue

}
Solution

  • I think problem is here

    verticalIndicator.backgroundColor = UIColor(red: 211/255, green: 138/255, blue: 252/255, alpha: 1)

    Change to 

    verticalIndicator.backgroundColor = UIColor(red: 211/255.0, green: 138/255.0, blue: 252/255.0, alpha: 1).

    The result of division 211/255 is type of integer so it return only 0 or 1 (in this case i think it is 0).
