According to the document, exifData is now provided for IOS 16 in ARFrame object. I'm saving the capturedImage in this way right now. How can I store the image with the corresponding exif data?

let ciImageColor = CIImage(cvPixelBuffer: frame.capturedImage)
let contextColor = CIContext.init(options: nil)
let cgImageColor = contextColor.createCGImage(ciImageColor, from: ciImageColor.extent)!
let uiImageColor = UIImage(cgImage: cgImageColor, scale: 1, orientation: UIImage.Orientation.up)

uiImageColor.jpegData(compressionQuality: 0.0)!.write(to: colorJpgURL)

Take a look at this Stackoverflow discussion: https://stackoverflow.com/questions/35758510/save-the-exif-metadata-using-the-new-phphotolibrary Seems like this should be doable via ImageIO's CGImageDestinationAddImageFromSource()
