Hi Cocoa developers,
I created a simple garbage collected Core Data application using the
Xcode template.
I did not change much except that I added an empty window controller
for my window,
which is the file's owner of my .xib.
I added logs in the init and finalize methods to make sure that each
object created was
eventually finalized. However, I realized that even if the document is
always finalized when
I close the window, its window controller is not. Let's say I open a
new document and close
it right away and repeat the operation a few dozen times, I end up
with all documents collected,
but a few window controller still to be collected. Even if I force the
collector, they are not collected.
Even stranger, if I delete my only entity from my .xcdatamodel (which
does nothing), then
everything gets collected as it should. How can a entity prevent an
object from being collected?
Am I missing something obvious here? Or should I consider it a garbage
collection bug?
I made a copy of my project available if someone would like to take a
look at it. It is quite simple.
