Hihi if I have an Aap that supports Core Data & CloudKit, and the device we t offline, when it's back online data will sync automatically?
Hihi I'm developing a patient management system using Code Data App that supports CloudKit, I feel it's the best scena to use, my concern is if a user a doctor for example is editing a record while another staff delete this record, what's the design pattern here ? Locking the record ? Can that be done in Core Data CloudKit ?Another concern is, what if a record is deleted and because there's few seconds of delay in data sync another user might open that record or at least try to open it ? Or maybe he edited it when he was offline and then when going online that record was deleted ?There might be many other such cases but what I understand that new systems solves this issues in a better why ?--Kindest Regards
