Swift 2.0 :

Add UIScrollView Delegate.

func scrollViewDidScroll(scrollView: UIScrollView){
let verticalIndicator: UIImageView = (scrollView.subviews[(scrollView.subviews.count - 1)] as! UIImageView)
verticalIndicator.backgroundColor = UIColor.greenColor()

let horizontalIndicator: UIImageView = (scrollView.subviews[(scrollView.subviews.count - 2)] as! UIImageView)
horizontalIndicator.backgroundColor = UIColor.blueColor()
}
