imageView with CGAffineTransform

[Mirach0rus]

How can I apply CGAffineTransform to imageView ImageViewerConfiguration ?
I try this

let configuration = ImageViewerConfiguration { config in
            config.imageView = imageView // my UImageView
            let angle: CGFloat = (270.0 * CGFloat.pi/180.0)
            config.imageView?.transform = CGAffineTransform(rotationAngle: angle)
}

but no effect

What kind of behaviour did you expect?
