Here is the answer with extension of Juan Ariza

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    let subViews: NSArray = view.subviews
    var scrollView: UIScrollView? = nil
    var pageControl: UIPageControl? = nil

    for view in subViews {
        if view.isKindOfClass(UIScrollView) {
            scrollView = view as? UIScrollView
        }
        else if view.isKindOfClass(UIPageControl) {
            pageControl = view as? UIPageControl
            pageControl?.pageIndicatorTintColor = UIColor.lightGrayColor()
            pageControl?.currentPageIndicatorTintColor = UIColor.blackColor()
            pageControl?.backgroundColor = UIColor.clearColor()
        }
    }

    if (scrollView != nil && pageControl != nil) {
        scrollView?.frame = view.bounds
        view.bringSubviewToFront(pageControl!)
    }
}

Try this:

pageControl = [UIPageControl appearance];

//for change the bullets color
pageControl.pageIndicatorTintColor = [UIColor colorWithRed:(129.0/255) green:(129.0/255) blue:(129.0/255) alpha:1.0];
pageControl.currentPageIndicatorTintColor = [UIColor colorWithRed:(06.0/255) green:(122.0/255) blue:(145.0/255) alpha:1.0];

pageControl.backgroundColor = [UIColor clearColor];
