First -- this has nothing to do with Xcode. It is a CoreData
question and you should probably take it to cocoa-dev.
To answer the question: More likely than not you created the data
file via Core Data using a model prior to the addition of the
MapCoordinates entity. CoreData does not have a data migration
feature and will not automatically track changes to your data model.
You need to either manually migrate the data or simply delete
previously created data stores.
This is getting me headaches. I believe this is the cause of the
following run-time error:
*** -[NSArrayController presentError:]: selector not recognized
[self = 0x388df20]
*** NSRunLoop ignoring exception '*** -[NSArrayController
presentError:]:
selector not recognized [self = 0x388df20]' that raised during
posting of delayed perform with target 38c49b0 and selector
'invokeWithTarget:'
Likely, it is the cause. I hate that particular error message. It
is remarkably opaque.
You can also run into this problem if you perform an action that
causes CoreData to generate a SQL query that tries to sort on a
transient or derived attribute; an attribute that doesn't exist in
the data store.
