Apple is ready to ask Developers to make improvements to incoming Mac Apps. Through the Apple Developers portal, Apple is asking OS X Developers to change the way their incoming apps treat memory. Rather than ‘Garbage Collection’, Apple is asking Developers to use Automatic Reference Counting (ARC) for memory management. The change applies only to incoming apps, and for apps submitted after May 1. Developers should have seen this coming, though; Apple began favoring ARC over Garbage Collection back in the days on OS X Mountain Lion.
