ios - iCloud updates only on app launch -

i have ios , osx app use core data , i'm trying sync them using icloud.

my problem when update in osx app, ios app show update after restart. i'm testing on device, ios 8.3, icloud drive enabled.

to investigate issue, added observers ios app relevant notifications, including nspersistentstoredidimportubiquitouscontentchangesnotification. called on sync happens when launch app.

i set debugging levels:

-com.apple.coredata.sqldebug 1 -com.apple.coredata.ubiquity.loglevel 3 

looking @ output, update osx app arrives - that's it. no notifications , when fetch data update not there. there after next time launch app.

i investigated bit further, there's folder in device .../appdata/documents/coredataubiquitysupport/

which seems contain icloud files, in store/ there's myappname.sqlite file in think app stores current icloud data. after logging of updates finished, downloaded file, opened sqlite , checked if tables updated , aren't. fails before writing icloud sqlite store?

this log see in console, don't see errors or warnings:
