Thank you for looking at this for me.
OS X 10.8.5 Mountain Lion
iOS Simulator 7.0 (4188.8.131.52), destination iPad
(Yes, pre-Mavericks version. I can test on an updated machine this weekend.)
Drop in grid framework, essentials framework, essentials bundle.
License keys 3 places.
It's possible that the new simulator has tried to implement the latest accessibility changes and has something broken:
The accessibility inspector launch does weird things to your normal interaction with the simulator. Click button, double click it to use the button, etc.
I don't have preloaded data on Grid 1 (that first shows), so you have to use the Add Records to Grid 1. When you get it working, the Add Records button has the accessibility descriptors implemented, so you can see what they should look like elsewhere.
I haven't had it crash on me just playing around, but it may not be properly releasing cells and overloading memory?
