Sven,

Thanks for the reply :)

I will try to move my code over to another image (I'm not very good with GitHub - we'll see how this goes).

But it just seems like there ought to be a way to at least delete all of these instances - as they are pretty easy to get ahold of (Class allInstancesDo:).�� But I can't find a way to delete them.�� I can count them, I can display content - attached is a screenshot showing for each Album instance, I can display it and data from it's embedded Artist and collection of Tracks.

Attached are a couple of screen shots��of the 'query' I mentioned in my previous note... as you can see - Tracks, Albums, (FileReference is my fault, also - I use those to hand music files to my objects for processing. Those are hanging around as well).

Hi Russ,

It is quite hard to debug somebody else's application, especially without access to the code, but here are some suggestions of what I would do.

Can you move your code to a new/fresh image and see what happens there (especially after just one iteration of loading your data) ?

Is there a difference between loading your data and opening your app with respect to the retention of garbage ? This would help to determine if this is a UI problem or a domain model problem.

There are tools that help you to figure out who holds a specific object ('Reverse pointers to' in the Inspector) but these are not so easy to use (you get lots of data).
