So your faces from Mac automatically synced to your iPhone? Is that because you're on macOS Sierra?
No, in fact from what I read it may be the opposite. I need sync my Mac and phone and I upgraded my phone before the Mac. Faces synced over icloud with iOS 9 and OS X 10.11 and it seems they were retained in the database on the phone because it had named faces quickly after upgrade. From what I've read there's currently no sync of memories or faces with iOS 10 and Sierra - that's what the release notes for Sierra say.
I think it'd be fair to say you should expect unpredictable and largely undocumented results for now with both betas early and in flux.
Interesting. What if I don't have a Mac? I guess it has to scan and match the faces from somewhere else - that's why I suppose contacts should have a contact picture for this to work.
Then you can do it right from iOS. Open a picture with faces, hit "Details", select the face and name it. I don't know if it does any of this automatically from contact pictures or not since, as I said, I don't use them I'm afraid.
1) Why couldn't face synchronization be end-to-end encrypted like iMessage?
2) I read somewhere that Photos app face syncing is specifically listed by Apple as missing from the current beta, suggesting it's planned for a future build.
1) dunno why it isn't or why they don't
2) yeah that was what the release notes said, not sure if beta 2 or 3 still has the same (not participating in the ios beta this go around).
Based on release notes this functionality still is not present on the current beta of iOS 10. Probably next beta I'd expect.
They talked a bit about why in an interview shortly after WWDC.
Aside from some technical reasons not yet solved. There is also the reason of. That's it's done in each individual device, on device. If someone has an iMac, iPad and iPhone. Which device then becomes the "master" device to sync to all other devices you own when they're all doing their own individual scanning?
I don't remember everything they said, so I'm sure I'm leaving some other things out.
This is my biggest issue with the new OS updates...it makes the feature much less useful as there's no incentive to fix bad results if I have to do it across three devices. They could have stuck to in device processing and allowed synchronisation within Apple Photos apps only, but stripped the metadata from any export.
The issue of what edit wins isn't a big deal, same applies to other file types. If they timestamped edits and whether the edit was made by iOS or the user, you could handle most cases with logic that the most recent user edit wins, and if no user edit has been made either the oldest or newest iOS edit wins. Sure you can create infinite "but what if" scenarios, but generally with these things simple logic that's deterministic works best.
The other thing that simplifies it is there is only one correct answer, a face will reference one person and it should always be the same person. There's more chance for ambriguity when dealing with say a text document where two versions are more likely to wildly diverge. On the chance the names don't match, maybe due to a typo or whatever, the photos apps have the ability to merge two faces anyway.
