You can't use passing by reference in C or Objective-C, you can with
C++ or Objective-C 2.0, for example the following will compile:

Note that references aren't fully supported by the lower level runtime
(though this may have improved). This includes using @encode on a
structure that has field that is a reference, and introspection of
method parameters. The latter mean that NSInvocation can't be used
with methods that use references (and since the undo mechanism is
based around NSInvocation, you can't use methods with invocations with
the undo manager).
There are/were similar problems with AltiVec/SSE vectors as well (and
other issues with templates).
