It’s because they use different Obj-C runtimes. For compatibility reasons, 32-bit Mac apps still use the old runtime, while 64-bit apps (and all iOS apps) get to use the new improved runtime. One of the differences between the runtimes is how instance variables are accessed, and I think your particular situation — trying to synthesize a property backed by an _inherited_ ivar — is an edge case. You could ask this on the objc-language mailing list to see if any gurus can weigh in. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
