Understanding Core Data

Hi All,

I have just worked through the diary app course using core data. I am just unsure of the instances where you would utilise core data to store data over something like parse, as we used in the Ribbit App?

Thanks, Alex

That's a good question and it completely depends on the app. Parse is a good service but the data resides in the cloud, which requires an internet connection. Your app will not be able to function when there is no internet connection. In addition, when a user opens up your app with a connection, you have to first download the data and then show it them.

Core Data resides locally on the device so there is no dependency on an internet connection and any interaction with the data is instantaneous.
