When to update local db(coredata) from server data for particular user?
I am working on mobile application in which we'll store data to local db. If a user changed his/her name or profile image from web. Then how and when, i'll update my record on local db for particular user?
Either will i have to check all record one by one or any other solution. Please suggest.
What should be the steps to update db?
