ObjectiveRecord nil model error - ios

Question

For the first time I'm trying to use CocoaPods and ObjectiveRecord. ObjectiveRecord's github page
When I try to save my object, I get the following error:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Cannot create an NSPersistentStoreCoordinator with a nil model'
*** First throw call stack:

This is what my Podfile looks like:
platform :ios
pod 'ObjectiveRecord'
I'm using the new xcworkspace file instead of the old xcode project file and I've imported the following two in the .pch file:
#import "ObjectiveRecord.h"
#import <CoreData/CoreData.h>
I've added Core Data in the project's settings page. Now when I'm using the provided code from the example of the github page:
Person *john = [Person create];
john.name = #"John";
[john save];
I get the error above. Have I forgotten something? I've been searching for some time now but I can't figure it out.
I'm using Xcode 5.0.2 and iOS 7.
Update:
It turns out that, in the general project settings, in the frameworks and libraries section, there is a red "libPods.a" entry. That means that it's missing, right? Could this be the issue?

Answer 1

From the doc:
Custom CoreData model or .sqlite database
If you've added the Core Data manually, you can change the custom model and database name on CoreDataManager
[CoreDataManager sharedManager].modelName = #"MyModelName";
[CoreDataManager sharedManager].databaseName = #"custom_database_name";
https://github.com/mneorr/ObjectiveRecord/blob/master/README.md
Reading docs will always help.

Answer 2

Ok, I fixed the error by renaming my Model.xcdatamodeld into appname.xcdatamodeld. I'm not sure why it fixed it but, I always named my models "Model" before, without any problems, but now it works. I hope this helps other people having this problem. I as well found out that the red colored "libPods.a" entry doesn't mean that it's missing. So even if it's red, everything is fine.
