I use the following code to parse Photo metadata and this works well. However, I am unable to pull the new iOS 14 "caption" from this metadata (it worked in early iOS 14 betas, but has since stopped working in the GM.) Does anyone know how I can get the caption data from a PHAsset? Thanks!

let options = PHContentEditingInputRequestOptions()
options.isNetworkAccessAllowed = true
asset.requestContentEditingInput(with: options, completionHandler: {(contentEditingInput, _) -> Void in
if let url = contentEditingInput?.fullSizeImageURL {
let fullImage = CIImage(contentsOf: url)
// get all the metadata
self.allPhotoMetadata = fullImage?.properties ?? [:]
// {TIFF}
if let tiffDict = self.allPhotoMetadata["{TIFF}"] as? [String:Any] {
if tiffDict["Make"] != nil {
self.cameraData[cameraKeys.make] = tiffDict["Make"]
}
if tiffDict["Model"] != nil {
self.cameraData[cameraKeys.model] = tiffDict["Model"]
}
if tiffDict["ImageDescription"] != nil {
self.imageData[imageKeys.caption] = tiffDict["ImageDescription"]
}
}
// {IPTC}
if let iptcDict = self.allPhotoMetadata["{IPTC}"] as? [String:Any] {
// if we didn't find a caption in the TIFF dict, try to get it from IPTC data
// first try, Caption/Abtract, then ArtworkContentDescription
if self.imageData[imageKeys.caption] == nil {
if iptcDict["Caption/Abstract"] != nil {
self.imageData[imageKeys.caption] = iptcDict["ArtworkContentDescription"]
} else if iptcDict["ArtworkContentDescription"] != nil {
self.imageData[imageKeys.caption] = iptcDict["ArtworkContentDescription"]
}
}
}
}
})
}
