I am using CKSIncrementalStore.

My datamodel is: DataModel

All attributes are optional.

I can create a client and after that create a project where I add the client as a relation.

Like this:

    project.client = client

It works fine as long as I only add the same client to one project. Every time I try to add a client to more than one project it gives me this error:

Error Domain=NSCocoaErrorDomain Code=1550 "The operation couldn’t be completed. (Cocoa error 1550.)"

I have the NSManagedObjectContext stored in a sharedManager so I use the same NSManagedObjectContext everywhere.

What might be wrong? :)

  • *"I use the same NSManagedObjectContext everywhere"*: Are you always calling it from the same thread? – Aaron Brager Jul 16 '15 at 18:17
  • I am not using threading, so I assume everything run on mainthread. :) – Nick Emil Starup Pedersen Jul 16 '15 at 18:34

  • @NickEmilStarupPedersen I wouldn't assume, since another library might be switching (you can check by logging `[NSThread isMainThread]` before you update your data model) – Aaron Brager Jul 16 '15 at 22:52
  • Other things to check: (1) the objects are actually the type of objects you think they are; (2) you aren't creating any invalid associations (like adding a client to a project that already has a client) – Aaron Brager Jul 16 '15 at 23:07
  • Okay, found out it is main thread. If I call TimeManager.timeManager.managedObjectContext!.insertObject(client) before setting the client to the project. The client get saved on the project. But then every time I do that a new client with all of the projects is also added. – Nick Emil Starup Pedersen Jul 17 '15 at 00:12
  • Okay, I its working until I restart the app, then it gives me this error: 'Cannot retrieve referenceObject from an objectID that was not created by this store'. Do I need to call something on the object before I edit/save it? Like refresh it? And if the clients have projects in NSSet do I need to refresh all of them?

It was an issue with the library. (:
