Ok. I added the code after I changed it. I didn't fill in the parameters.

Yes. I got that. I noted in my post that property is of type NSObject in my managed object class. I don't know what to set it to instead of NSObject.

Those are hacks. Surely Apple has an official fix for this.

I think you are mistaken. I clicked the option "Remove App", and I got a message saying that app name will be released to other developers and put in my removed apps list. I think you are correct that I can add that app back anytime, just that I might have to use a different name if another developer decides to use the name I had been using before I removed the app.

I figured out that I had made a mistake in how I added to a relationship. When I changed the code to add to the relationship using the add method of the managed object subclass, the error disappeared.

Ok. Thank you very much.

Thank you DelawareMathGuy.

Thank you everyone Claude31 and eskimo!

I would like to be able to reference the subclass and access the fields as properties of the subclass.

I found the documentation. That's not what I need.

Yes. I am not sure what that does. I can't find documentation on it.

I figured it out. I needed to set cancelsTouchesInView property of the gesture reconginzer to false.
