WARNING: There are at least two issues with this workflow.
1. Not all images that appear in iOS UI for “All Photos” are actually available for import into Aperture. I suspect images that have synchronized from iCloud Photo Library are stored in a different physical location from the images Aperture sees.
2. Neither Aperture nor Image Capture can delete photos from iPhone if iCloud Photo Library is active. Aperture doesn’t show an error message but fails. Image Capture doesn’t show the delete control. Turn off iCloud Photo Library to reenable delete.
———- ORIGINAL POST ——————-
With El Capitan it is possible to have Photos.app and iPhone share photos via iCloud, while Aperture owns posting to iCloud photo sharing streams. You have to fight Photos.app a bit, but it works great.
So my workflow has been to use Photos.app on OS X and iOS to cull images, then periodically export from Photos.app to Aperture. Except Photos.app original image export is broken, and has been broken since 1.0. (Exports all images, even those that are “deleted”), so this is a pain.
Finally realized there’s a much better solution. Whenever I want to move images from Photos.app to Aperture I import them from the iPhone into Aperture (iPhone set to keep full res images). Then I use Aperture post-import delete. Then they delete from Photos.app. Much neater.
