Does the number 1 imply that it's version 1 of the mode and there may
be multiple versions supported at the same time? Or was it for
Objective C Runtime Library 1.0 ? (I am almost sure that not)
It means/meant version one of the Objective-C language. The Objective-C
language evolves semi-independently of the run time (you can write programs in
Objective-C 2.0 running on i386 and ppc32, whose Objective-C runtime is version
1). Objective-C 2.0 (the language) features require Mac OS X 10.5 or later,
while 1.0 features are available as of 10.0.
Eh ?
How can a programming language feature depend on an operating system ?
Keep in mind you can add methods runtime in objective C. IOW a library can
construct tobject differently.
Yes, but that is a run-time feature, not a language feature. The language
feature
states that you can add methods runtime. What you do with it is no longer a
language
feature, I would think ?
Michael.
