#2Good time to check out ObjFW [1], it's a cross platform ObjC framework that's just really awesome
Re: Why Objective-C
#3I really miss Objective-C, and in the world of Swift craziness [1] I'm reminded often of this blog post [2] wondering what would have happened if Apple hadn't encountered Second System Syndrome for its recommended language.
(There's a decent argument it encountered it in iOS and macOS too.)
[1] https://github.com/swiftlang/swift-evolution/blob/main/propo... -- apologies to the authors, but even as a previous C++ guy, my brain twisted at that. Inside Swift is a slim language waiting to get out... and that slim language is just a safer Objective C.

#4I still find Objective-C++ useful for writing MacOS apps that make heavy use of C++ libraries (e.g.; Eigen, OpenCV). The caveat is I have done a lot of Objective-C programming and Swift is still not as seamless as I would like bridging with modern C++ and the the STL.

#5> [[those squareBrackets] lookInsane:YES].
Nah, they are perfectly sane. They look like little ASCII envelopes because that's exactly the metaphor. Square brackets send messages.

I hadn't come across this. Insane (if true, I've never tried) that GnuStep is not 100% compatible, surely that would be the point.
How easy is it to port, say, a Leopard-era Objective C app to ObjFW?

#7At this point in my career, I can't go back to a language that doesn't have support for Optionals or compiler validation of nullable types. I can sacrifice async or fancy stream apis, but I will never go back to chasing null pointer exceptions on a daily basis.

Yeah, Objective-C++ is surprisingly great. It sounds like a terrible idea, but the bridging works pretty much seamlessly, and Obj-C and C++ don't actually overlap all that much so they don't step on each other's toes. Each language has strengths that shore up the weak spots in the other.

#9I bounced off of Objective-C not because of its message-passing OO. That was the actual cool part. I bounced off because of the insane amount of boilerplate prototyping and headers required to use it.
I think every OO language should be using Smalltalk's message-passing style rather than holding hard references, and Objective-C is a great model. But discard the rest.

+1 to Objective-C++. It makes for some surprisingly clean, compact code, best of both worlds, really. And the bridging between ARC and CF types is really quite magical, more languages should have that ability to be expressed in an older language without stripping everything out.
I just wish there were Objective-C bindings for more CF classes without having to mess with C.
