comment Update Managed Objects in Managed Object Context After Batch Update
You seem to misunderstand. You should use the root context and ensure all objects as faults. Objects that are not faults are the in memory representation. If the context has an in-memory copy of an object, it will use it. If it is a child context, it will pull the object from it's parent. Fault the objects. Faulting is a fundamental concept in Core Data.

I have. Make sure it's the root context, and all objects are faults

comment Core Data iOS 8 Today Widget issue
Your app and your widget run in different processes. If your app changes the core data store, your widget will not get a notification sent from the app.

comment NSManagedObjectContextObjectsDidChangeNotification for one entity
Note that it is best to look for the NSManagedObjectID rather than the NSManagedObject in the change notification userInfo.

comment Definition of Boolean with Core Data
This has always been the case. In the iOS 8 SDK the accessor method "isUpdated" was redefined as a readonly property. -isUpdated has always returned BOOL, and should not be overridden.

comment NSFetchRequest returning array with elements of type <invalid>
This is an issue with the debugger and/or the -description method of the managed object.

comment NSFetchedResultsController with predicate ignores changes merged from different NSManagedObjectContext
mergeChangesFromContextDidSaveNotification: performs (almost) the same process as processPendingChanges, and posts the appropriate notification.

comment crash on coredata ios8
The parser that is taking your fetch request and turning it into SQL is interpreting part of your fetch as a nil string, which isn't being caught (or checked) by the framework, resulting in your crash. PLEASE file a bug!
