Hi Hunter,
I am very interested in what bugs they fixed. Could you please share more
about it , e.g. an official bug fix report ?
Thanks
Bob
The API changes came in iOS 5 but in iOS 6 they fixed enough bugs to make it
work right. :-)

I'm seeing a substantial degradation in Core Data fetch performance after just
a few thousand objects, in the simulator on a beefy MacBook Pro.
My app loads data from the web, then uses an integer key in each downloaded
record to find the local record in Core Data. So I do a lot of queries like
= [[possibleEvents filteredArrayUsingPredicate:
indexMatchPredicate] lastObject];

Heh, I re-read your post like four times and only just now saw that notation.
Whoops.

I do. I was thinking about this last night. I'm concerned that this may
require too much memory, and building a string of 6400 IDs for the query to
then format...sounds expensive. Can one build IN queries directly?
I should note, I've done this quite successfully with workloads in the ~500

I'm not entirely sure I know what you mean by 'directly' in this context.

Hi all,
I have 2 CoreData entities, Foo and Bar. Both have 'name' string
attributes. There are textfields allowing the user to rename any Foo
and any Bar. Assume no 2 Foos can have the same name; likewise for
Bars. There is a relationship between Foo and Bar. I want a Foo to be
related to a
