From the Xcode 4.4 release notes: GCD and XPC objects support Automated Reference Counting (ARC) in Objective-C. Using GCD and XPC with ARC requires a minimum deployment target of OS X10.8 and is disabled when building with Garbage Collection or for 32-bit Intel. It can be manually disabled by adding OS_OBJECT_USE_OBJC=0 to the "PreprocessorMacros" build setting in Xcode. > Thanks again, > > Jerry > > > _______________________________________________ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > https://lists.apple.com/mailman/options/cocoa-dev/devlists%40shadowlab.org > > This email sent to devli...@shadowlab.org -- Jean-Daniel _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
