I have noticed that for a mobile application, saving on the main thread seems to take a bit when it compares to other applications on the device. Is it recommended to only save Core Data when the application enters the background or when an application closes instead of anytime items are added and sent / received from the api?
That's kind of a broad question, but I've found that saving core data after VewDidAppear statements is better than viewWill statements. Giving the user something to engage with and persisting makes it less noticeable than on a load. However, if a user is used to waiting for something like an activity loop, adding the save to that doesn't tax it too much (IMHO).
