I decided to manually switch the project to ARC. So I set the SDK and target to 10.7, build for 64 bit only, and enabled ARC. Clean and build - but it didn't work (I added "has_feature(objc_arc)" tests all over.


ARC didn't take - sorry to be so obtusive. In other words, I had this block header of "#if ! __has_Feature(objc_arc)", and it tripped. I then added a [someObj retain] and got no complaint.


Sooooo - is there some hidden flag, or some magic that must be done to make the switch manually? I'm like 99% sure I've manually converted iOS projects, but I have so few OSX projects now so no prior experience.


Did you switch the compiler to LLVM Compiler when things weren't working?

Compiler was set to llvm - I checked. Don't think there is another option now is there? [llvm with gcc frontend?]. I always just use ARC.

I probably can reproduce since the project was under source control. I just could find no setting that had changed after I did the refactor. That said, I closed and reopened the project but did NOT restart Xcode.

I tripple checked the project AND the target settings too. Looked to see if somehow the files were marked with 'fno-objc-arc" in the Build Phases. It was just plain bizarre.
