There is definitely a save happening, because the CDESaveMonitor is catching the notification. I would double checked, perhaps set a break point and catch the did-save notification to see where it is saving.
Thanks. That got me looking in the right direction. My app was setting up ensembles twice which seems to have been causing the issue.
I have integrated Ensembles using the examples provided in the documentation. Syncing works well at first, but always ends in one device getting an - Error merging: Error Domain=CDEErrorDomain Code=207 "The operation couldn’t be completed. (CDEErrorDomain error 207.)". According to the explanation, this error means that a save to the persistent store occurred during merge and we should retry the merge.
Even after retries, the merge never succeeds. This seems to permanently break the sync. I have placed log statements to make sure I am not saving inadvertently. What else could cause this error?
