Objective-C 2.0 provides an optional conservative, yet generational garbage collector. When run in backwards-compatible mode, the runtime turns reference counting operations such as "retain" and "release" into no-ops. All objects are subject to garbage collection when garbage collection is enabled. Regular C pointers may be qualified with "__strong" to also trigger the underlying write-barrier compiler intercepts and thus participate in garbage collection. A zero-ing weak subsystem is also provided such that pointers marked as "__weak" are set to zero when the object (or more simply, GC memory) is collected. The garbage collector does not exist on the iPhone implementation of Objective-C 2.0. Garbage Collection in Objective-C runs on a low-priority background thread, and can halt on user events, with the intention of keeping the user experience responsive.
