Editing Garbage collection (computer science) (section)

=== Objective-C ===
While the [[Objective-C]] traditionally had no garbage collection, with the release of [[OS&nbsp;X 10.5]] in 2007 [[Apple Inc.|Apple]] introduced garbage collection for [[Objective-C]]&nbsp;2.0, using an in-house developed runtime collector.<ref name="Leopard"/>
However, with the 2012 release of [[OS&nbsp;X 10.8]], garbage collection was deprecated in favor of [[LLVM]]'s [[Automatic Reference Counting|automatic reference counter]] (ARC) that was introduced with [[OS&nbsp;X 10.7]].<ref name="Siracusa_2011"/> Furthermore, since May 2015 Apple even forbade the usage of garbage collection for new OS&nbsp;X applications in the [[App Store (iOS)|App Store]].<ref name="Appleinsider_2015"/><ref name="Cichon_2015"/> For [[iOS]], garbage collection has never been introduced due to problems in application responsivity and performance;<ref name="wwdc_2011"/><ref name="Silva_2014"/> instead, iOS uses ARC.<ref name="Napier-Kumar_2012"/><ref name="Cruz_2012"/>
