Since iOS 13 I can't get original-res versions of photos in My Photo Stream using PhotoKit. I've had several complaints from users over the last few months, so it's not anything specific to my own device or account. The following code always retreives very small images (e.g. 360 x 480).
PHPhotoLibrary.requestAuthorization({ status in
DispatchQueue.main.async {
if status == .authorized {
// if iCloud Photo Library is disabled and Photo Stream is enabled this will give you My Photo Stream
let photoStream = PHAssetCollection.fetchAssetCollections(with: .album,
subtype: .albumMyPhotoStream,
options: nil)
if let photoStreamCollection = photoStream.firstObject {
let res = PHAsset.fetchAssets(in: photoStreamCollection, options: nil)
if let asset = res.firstObject {
let opts = PHImageRequestOptions()
opts.deliveryMode = .highQualityFormat
opts.isSynchronous = true
opts.isNetworkAccessAllowed = true
opts.resizeMode = .exact
print("asset size: \(asset.pixelWidth) x \(asset.pixelHeight)")
PHImageManager.default().requestImage(for: asset,
targetSize: PHImageManagerMaximumSize,
contentMode: .default,
options: (img, info) in
if let img = img {
print("image size: \(img.size.width * img.scale) x \(img.size.height * img.scale)")
}
}
PHImageManager.default().requestImageDataAndOrientation(for: asset, options: opts)
{ (imgData, dateUTI, orientation, info) in
if let imgData = imgData {
if let img = UIImage(data: imgData) {
print("image size: \(img.size.width * img.scale) x \(img.size.height * img.scale)")
}
}
}
}
}
}
}
})
asset size: 1536 x 2048

I've tried every conceivable combination of options in PHRequestOptions. Note that if I set opts.version = .original it gives me a nil image and nil image data.
I've also tried asset.requestContentEditingInput(...) to try to access the image URL directly and I get this error in the console:

Interestingly, UIImagePicker does retrieve the original-res image (e.g. 1536 x 2048). The Photos app also shows the full-res image.
