Is Better csv or sqlite for preload data into Core data? <p>I have to preload data into my core data to have always my entities full of data, since the first time someone start the application. I have a database in csv and other sqlite. which is the best? and How should I do it? I mean, I guess I should have my database always in a folder of my app and the first time I launch the app I will fill data into database. isn't it? or I am wrong? if this is the good way? How I do it? </p>
