Hi,

Not sure how to describe my issue best: I am using SwiftData and CloudKit to store my data.

In the past, when I tested my app on different devices, the data would sync between the devices automatically. For whatever reason this has stopped now and the data no longer syncs. No matter what I do, it feels as if all the data is actually stored just locally on each device.

How can I check if the data is actually stored in the cloud and what could be reasons, why its no longer synching between my devices (and yes, I am logged in with the same Apple ID on all devices).

Thanks for any hint!

Just to add that SwiftData + CloudKit uses NSPersistentCloudKitContainer under the hood, and so the technotes my colleague mentioned apply to your topic. Specifically, you can use CloudKit Console to determine if the data is synchronized to CloudKit. From there, you can determine if the issue happens on the exporting or importing side, and go ahead to capture and analyze a sysdiagnose, as described in the Capture and analyze a sysdiagnose section.
