Try this out

func imageWith(image : UIImage, scaledToSize:CGSize ) -> UIImage {
    UIGraphicsBeginImageContextWithOptions(scaledToSize, false, 0.0);
    image.drawInRect(CGRectMake(0, 0, scaledToSize.width, scaledToSize.height))
    let newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return newImage;
}


var image = UIImage(named: "thumb.png")
slider.setThumbImage(imageWith(image, scaledToSize: <YOUR_SIZE>), forState: UIControlState.Normal)
