os/object.h

@header @preprocinfo By default, libSystem objects such as GCD and XPC objects are declared as Objective-C types when building with an Objective-C compiler. This allows them to participate in ARC, in RR management by the Blocks runtime and in leaks checking by the static analyzer, and enables them to be added to Cocoa collections. NOTE: this requires explicit cancellation of dispatch sources and xpc connections whose handler blocks capture the source/connection object, resp. ensuring that such captures do not form retain cycles (e.g. by declaring the source as __weak). To opt-out of this default behavior, add -DOS_OBJECT_USE_OBJC=0 to your compiler flags. This mode requires a platform with the modern Objective-C runtime, the Objective-C GC compiler option to be disabled, and at least a Mac OS X 10.8 or iOS 6.0 deployment target.
