How to copy an object between 2 NSManagedObjectContext
How to copy NSManagedObject
from one NSManagedObjectContext
to another?
I have 2 different ones NSManagedObjectContext
, each with its own NSManagedObjectModel
and separate permanent store. Each of the 2 MOCs has an object named Observation
that is tied to the same Observations class.
I want to copy objects from one MOC to another. Since the objects are of the same class, I would like to simply extract the object from one MOC and store it in another. Is this possible, or do I need to insert a new object into the target MOC and then set each property one at a time?

You need to copy one object and paste a new one into another managed object context. You will most likely have to copy property values one at a time to do this.
The reason is that all of these objects have an opaque unique identifier, so you cannot just take it from one context to another.
