iOS does not preserve GPS metadata from images picked from the Photo Gallery

Images picked from the gallery do not preserve metadata when saved to tmp. Particularly they lose GPS metadata.

This extra metadata is available in asset.defaultRepresentation.metadata.

I have a solution that works for my purpose. But currently only saving with asset.defaultRepresentation.fullResolutionImage.

Approach to get the asset: https://github.com/foundry/UIImageMetadata

Thanks for consideration.
