Automatic Reference Counting (shortly named ARC), is a new feature
that we can use developing apps for the latest iOS versions. Prior to
ARC, developers had to do all the memory management manually.
The way we allocate memory for an object in memory is by calling the
alloc method on for that object, and the way we initialise that object
is by calling the init method.
All the time, when we manage memory by ourselves, we should call the
release message to the objects that were allocated by us - one release
call for each alloc/init combination.
It is a very good practice, and also, this will prevent the memory
leaks in our apps.
When using ARC, if we try to call the release method, we get a
compile-time error, because the compiler does not allow that, as it
automatically inserts that for us.
