Swift: Image not cropping with .cropping(to: )

Question

I am trying to crop an image and the output is the exact same as the input. I know where the issue is but I cannot figure out why it is not working.

Here is the func:

    private func cropImage(image: CGImage, completion: @escaping (_ croppedImage: UIImage) -> Void) {
        let imageScale: CGFloat = max(CGFloat(image.width) / 1080, CGFloat(image.height) / 1920)
        print("imageScale: \(imageScale)")
        let cropRect = CGRect(x: 0, y: 0, width: 1080, height: 1920)
        print("cropRect: \(cropRect)")
        let cropZone = CGRect(x: cropRect.origin.x * imageScale,
                              y: cropRect.origin.y * imageScale,
                              width: cropRect.width * imageScale,
                              height: cropRect.height * imageScale)
        print("cropZone: \(cropZone)")
        if let croppedImage: CGImage = image.cropping(to: cropZone) {
            print("croppedImage: W\(croppedImage.width) H\(croppedImage.height)")
            var image: UIImage = UIImage()
            if self.currentDevicePosition == .front {
                image = UIImage(cgImage: croppedImage, scale: 1.0, orientation: .leftMirrored)
            } else {
                image = UIImage(cgImage: croppedImage, scale: 1.0, orientation: .right)
            }
            print("uiimage scale: \(image.scale)")
            print("uiimage size: \(image.size)")
            completion(image)
        }
    }

Here are the print statements:

imageScale: 3.7333333333333334
cropRect: (0.0, 0.0, 1080.0, 1920.0)
cropZone: (0.0, 0.0, 4032.0, 7168.0)
croppedImage: W4032 H3024
uiimage scale: 1.0
uiimage size: (3024.0, 4032.0)

Based on what I am seeing from the print', it appears that everything is working correctly until "if let croppedImage: CGImage = image.cropping(to: cropZone)"

The cropZone is giving me a new ratio that is correct, but simply nothing changes to the image.
