The one caveat here is that, because Apple only really allows certain apps the privilege of running in the background without being interrupted or killed, I could never get the iOS version of Immich to reliably sync photos without having to manually open it and leave the app open until sync finished.
This was a few years ago, and was one of several "iOS breaks our crucial workflows" problems that motivated switching our last device over to Android, so the situation might be better now...but I've never had that problem with the Android client, so I know it's not an Immich problem.
It works fine! The cost is a notification that the sync is running.
You don’t need to run your app in the background. You can register your app as some extension to handle photo backups/cloud storage and you just setup a request to upload to a particular url when a new photo is added, iOS will background those requests and retry them and what not.
