I implement UISlider with minimumValueImage and maximumValueImage as tappable button. I can get minimumValueImage and maximumValueImage by this way until iOS13. @IBOutlet weak var slider: UISlider! var images: [UIView] = slider.subviews.filter({$0 is UIImageView}) However, I can't get images by this way at iOS14 beta. I tried to find the way to get the information, below way seems to success to get images. images = slider.subviews[0].subviews.filter({$0 is UIImageView}) It looks structure of UISlider is changed. I checked API documents or forums but can't find information related this. (There are no changes based on this site.https://developer.apple.com/documentation/uikit/uislider?changes=latest_minor) Do you have any idea about this behavior ? Thank you very much in advance.
