title: Core Data: how to just delete and rebuild the data store?
body: <p>I'm using <code>Core Data</code> in an iOS 7+ app that does not need to save user's data, all data the app needs is requested to services and it can be recovered at any time. So, if I change my data model in a next app update, I have no problem in deleting all the previous data and requesting it all again. But I don't know how to simply replace the previous data model with the new one, without performing a migration since it looks that I don't need to do that...</p>
  
  <p>Thanks in advance </p>
