Simulator/device does not sync with iCloud

Question

From time to time I'm getting errors that my iOS 8 device or simulator will sometimes not sync with iCloud (Drive). The following message appears (multiple times) in the output log:

CoreData: iCloud: Error: failed to receive initial sync notification call back in 90 seconds

Only reinstalling the app helps. Has anyone experienced the same issue or got some information about this?

Yeah, I'm seeing this too. This happens on iOS 8 simulator but not iOS 7 simulator. Device seems to have no problem and regularly syncs after a set interval which is good to see. – Glaser

Answer 1

I have seen that error (today) on an iPad running iOS 8. I fixed it by performing a reset (hold power and home/sleep buttons until the Apple logo appears). After that when I reran my app it synced immediately.

For the simulator it may be sufficient just to quit the simulator and relaunch. However, I have seen cases where restarting the computer was required.

I'm not sure what the cause of the issue is but hopefully the above help.

Thanks! Was having the same issue on my iPad today! Saved me some time... :) – Bickart

I managed to get a re-sync in the simulator by going to settings -> my apple id account (first option) -> iCloud, and then disabling and re-enabling the "iCloud Drive" option. – Farrell

That worked forever, disabling iCloud Drive and then enabling. However, it looks like it does not work anymore. This seems totally unpredictable now. – Masseuse

Answer 2

I had the same issue on my simulator. Logging in iCloud on the simulator solved the problem. This was not obvious as there was no mentioning or request. Just browsed backwards until I was in Locations, selected iCloud and the simulator asked me to sign in.
