CoreData: Failed to load o

Answer 1

I want to answer to people who ran into this when was writing own pod which has own CoreData models. Probably, you've put your model definition to the bundle (that's good), but you search for the momd file in the wrong bundle.

Let's say you have defined your bundle in podspec like this:

'MYPodBundle' => [
    'Model/*.{xcdatamodeld,xcdatamodel}'
]

Then you should first find this bundle, and then locate your model inside it.

NSURL *bundleURL = [[NSBundle bundleForClass:[MYEntity class]] URLForResource:@"MYPodBundle" withExtension:@"bundle"];
NSBundle *bundle = [NSBundle bundleWithURL:bundleURL];
NSString *modelPath = [bundle pathForResource:@"MYCoreDataModel" ofType:@"momd"];
NSManagedObjectModel *managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:[NSURL fileURLWithPath:modelPath]];

So you can continue creating CoreData stack.
