The only solutions today I have , is to add manually the documents...with I click on the M icon and the option "source control > stage changes in "xxx"

Yes it's exact. I would like to change only the selected cell not others background but I do not want to change the moving cell !

..

Yes, I'm on real devices : iPad, wifi connected, iCloud signed..."check if the container is pointing towards the correct iCloud container", could you explain in detail? the container (NSPersistentCloudKitContainer) is towards to a container in cloud, all my devices are synchronize well...iPad/iMac/iPhone

Application supports iTunes file sharing is necessary to add into plist.info

thanx for your response, If I understand, I need to introduce a new tuple as you describe myNewID = (NSUUID, Int64ID) NSUUID will represent the ID for ipad --> unique even across devices = UUID().uuidString Int64ID will represent the interna increment ID --> unique Integer just for the local DataBase (as now) so iPad 1 will create record ID = xx-xxx-xxx-xxx-1 iPad 2 will create record ID = yy-yyy-yyy-yyy-1
