Summary:
Auto-generating an NSManagedObject subclass in Swift does a pretty good job.
However, if you try to use the objects as-is (like in a simple fetch), it will cause an exception because it cannot find the entity with the name.
This is always fixed by putting @objc(MyClass) above the class delcaration, such as:
@objc(BlogPost)
class BlogPost: NSManagedObject {
...
}
It would be nice if these could be generated automatically, and I wouldn't be surprised with a crash every time I change my data model :)
