I have used SAVideoRangeSlider in swift code works fine, but when i change url from didSelectRowAtIndexPath slider does not change thumbnails with new URL. So can you help me for this issue? Here is my code which i have implement
let cgrect = CGRect(x: videoPlayerView.frame.origin.x, y: frameContainerView.frame.origin.y, width: self.view.frame.size.width-40, height: frameContainerView.frame.size.height)

    slider = SAVideoRangeSlider(frame: cgrect, videoUrl: self.videoURL!)
    slider.bubleText.font = UIFont.init(name: "Helvetica", size: 10.0)
    slider.setPopoverBubbleSize(90, height: 60)
    slider.topBorder.backgroundColor = UIColor(red: 0.996, green: 0.951, blue: 0.502, alpha: 1)
    slider.bottomBorder.backgroundColor = UIColor(red: 0.992, green: 0.902, blue: 0.004, alpha: 1)
