    1. COShow your code for setting up Core Data, as well as for `[SNServerChanges newItemWithJSONStringFor:withList:]`. Are you trying to add an entity to a persistent store that is using your application bundle? (In other words, are you trying to *write* to your app bundle instead of to your application's Documents directory?)

    3. COI got that crashlog from AppStore App, so I don't have any more verbose information. I try to make that again on Debug, but as I said earlier that error occur very rarely.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
