[Interest] [OSX/iOS] Garbage collection still in place in Qt?

> This does not prevent applications from using ARC since it can be enabled per translation unit. We would like to start using ARC internally in Qt as well, but the requirement to drop 32-bit support may be too steep at this point in time. (Question for interest@: is 32-bit support important?)

Adam has already answered this for our company.

I note also that QMacStyle uses HITheme API's as well. I haven't been able to find NSThis or NSThat replacements for drawing pictures of controls and window elements, either.
