Force iCloud Drive to sync under Yosemite

There are many questions of forcing iCloud to sync, but they are generally old and unclear as to the details.

I changed the file structure at my Mac, but the iOS App (Pages) doesn't seem to take the new update.

When I look through the folder structure via another iOS App, there is still the old structure. So it seems that my changes on the Mac didn't update yet.

Is there a way in Yosemite to force the iCloud sync?

There has to be a service which is triggered and runs in the background. Which service is it?

Yes. The sync process is kicked off when you disconnect from all networks and then reconnect. You can debug things using brctl log -w on the Mac and AppleCare can also help you with iOS cloud sync diag logs if you have an issue that needs that level of debugging.

The brctl man page has information on diagnostic files and you can also use sysdiagnose to assist with cloud sync diagnosis.

The actual sync daemon is bird but you don't run it directly.

Lastly, before digging into the logs, I often use https://iCloud.com to verify that the Mac and iOS devices are either in sync with the cloud version so I know which of the three is lagging.
