NSManagedObject is failing isKindOfClass test

Vote count:

I have an NSManagedObject. When I create an instance, it fails the isKindOfClass method unexpectedly.

NSEntityDescription *entity = [NSEntityDescription entityForName:@"DayModel" inManagedObjectContext:context];
DayModel *day = [[DayModel alloc] initWithEntity:entity insertIntoManagedObjectContext:context];

if ([day isKindOfClass:[DayModel class]]) {
    NSLog(@"True");
} else {
    NSLog(@"False");
}

Output:

False

I added the following code:

Class objectClass = [day class];
Class classClass = [DayModel class];

And looking at it in the debugger this is what I found:

Printing the description of classClass prints "DayModel."

I'm not sure this is relevant, but DayModel is implemented in Swift.
