Last night I search around for this topic and found a lot of pre-CloudKit comparisons talking about how slow iCloud sync was. I had similar experiences with iCloud syncing, going from Dropbox to iCloud a few years ago. It was a garbage experience. Well I just tried the newer CloudKit based iCloud sync. Omg. It’s blindingly fast to sync. Had zero issues and it just works. Just thought I would mention it.
Thanks for sharing your experience!
We too have seen and heard reported mostly very good things about the CloudKit sync.
Is it correct to synced database with large volume of indexed files(in dropbox) within two Macs via icloud_kit ?
I am so afraid for duplicates or other unknown problem to corrupt the database.
Yes, this is possible to do and shouldn’t generate duplicates.
