Our final step in breaking the logic into layers is ensuring all database, network, translation concerns are housed only within the specific layers. When an application is created with Core Data, XCode adds the Persistent Container in the app Delegate. This type of implementation detail needs to be isolated within the Core Data layer only. Translation to and from Core Data, as well as JSON form the web server needs to be isolated into a Translation Layer. The Translation Layer is then further broken into supporting classes the deal with specific Entities and forms of data (JSON, Core Data, SQLite, etc.). The important part is to break apart the logic into single responsibilities.
