What’s the use case here? ARC and MMR are completely interoperable. When would you need to compile a file under both? If it’s legacy and needs to build under a really old compiler then you don’t convert it to ARC and you always compile it non-ARC, once it’s converted you always compile it with ARC no matter what you’re doing for other files in the project. As for why - the rationale is in section 7.1.1 of the arc spec http://clang.llvm.org/docs/AutomaticReferenceCounting.html <http://clang.llvm.org/docs/AutomaticReferenceCounting.html> and the following section for dealloc. It’s specified that code is ill-formed if it includes any of those and so the compiler has to follow the spec to it can’t ignore them. You may or may not agree with the rationale, but at least the specifiers of the language did write down why it’s that way. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
