Hi, I’m working on a photo backup app.
I track the PHAsset localIdentifier to determine which photos have been backed up and which haven’t.
Recently, I’ve noticed that two users seem to have experienced the localIdentifier changes after transferring data to a new iPhone using Quick Start.
Additionally, others on StackOverflow have mentioned that the localIdentifier sometimes changes after updating the iOS version.

I’d like to confirm the reliability of the localIdentifier after an iOS version upgrade or device transfer.
Can I continue using these locally stored localIdentifiers?
Or is there another recommended approach, such as using PHCloudIdentifier?
