Another case where people confuse the mechanism with the goal. ARC is not a full garbage collector. I'm not sure if this is worthwhile to build.). Like garbage collection, ARC frees the programmer .. In typical memory management implementations, memory is automatically garbage collected when the last reference to a variable is removed. When I wrote a garbage collector for a toy project, I used the twospace algorithm for its simplicity. Conclusion Automatic reference counting substantially reduces the burden on the programmer for dealing with memory management. Thankfully, modern languages with automatic garbage collection avoid this problem (by pretending it doesn't exist). It doesn't support automatic garbage collection, one of the most important features introduced in Java. ARC occupies a middle ground between garbage collection and manual memory management. Right now it doesn't, but in theory it could fall back to the dynamic subclass craziness for those classes. C++ supports dynamic memory allocation with the help of new and delete. Back to basics: Series on dynamic memory management. Perhaps this was a decent reaction to the memory management of C, but as a whole, in general purpose languages, garbage collection is more of a detriment than a benefit. Furthermore, the simplified model requires hiding the true nature of memory making it more difficult to implement certain inter-process and concurrent programming algorithms.
