I have WebView, which I want to change his size. I use CGAffineTransform looks like - let transform: CGAffineTransform = .init(scaleX: 0.2, y: 0.2) UIView.animate(withDuration: 0.5) { webView.transform = transform } Then I get a true result - my webView's frame is changed, but content size in the webView has not changed. When I use - UIView.animate(withDuration: 0.5) { webView.frame = CGRect(...) } My webView's frame is changed, but content size in the webView IS CHANGED. How I can get result for changing frame like using CGAffineTransform?
