Hi systems programming guys. I’m exploring the macOS as a low-level itself, so when I use the otool(1) utility to inspect a tiny objc helloworld program, it told me that there is a shared library like /usr/lib/libobjc.A.dylib (not identical) but I didn’t find that in path /usr/lib/. Also the docs sucked (see below). I want to know more details about the objc runtime on macOS (beta 27.6 +) and be seeking for help here because there are few materials online and not even to say the sucked AI.
The prima motivation is the runtime itself and how it works. Of course I would love to read disassembled code and manpages or using utilities that Apple offered to understand those things . But I really don’t know where is the runtime if both docs and otool output lied.
The latest documentation about Objective-C Runtime is outdate and it said “Objective-C runtime library support functions are implemented in the shared library found at /usr/lib/libobjc.A.dylib.”
