I like iCloud but it is only an add-on sync option for most games we do as they are android/ios/web/desktop. A non fully cross platform cloud sync option just doesn't help speed up development much but it s a great low barrier sync for iOS only customers.

For iOS it is pretty easy though, anything in Docs gets synced if logged in and the app is setup for iCloud. It has always been a little touchy when they added the Caches/Documents requirements. You have to setup a no backup flag to prevent it from syncing if storing anything there which can be a problem if you store too much.

    BOOL success = [URL setResourceValue:[NSNumber numberWithBool:YES] 
        forKey:NSURLIsExcludedFromBackupKey error:&error];
