Tip: Automatic Reference Counting

As defined on Wikipedia, Automatic Reference Counting (or ARC) is a “memory management enhancement where the burden of keeping track of an object’s reference count is lifted from the programmer to the compiler.”

With object-oriented programming, each new object you create takes up space in memory. This memory needs to be managed somehow. In the beginning, this management of memory was left entirely to the programmer, such as with C++ or originally with Objective-C.
