> It’s really a testament to the Objective-C runtime (and Ruby C extension API) that while much of the original code was written in 2001, an incredible amount of it runs unchanged over 20 years later on modern versions of macOS and Ruby. This is one of the things I love. Starting in 2014 with the introduction of Swift and continuing to the present, I've heard people claim that every line of Objective-C code you write is technical debt, but the opposite turned out to be true: any Swift code you wrote in the early years is now completely unusable. Apple even removed some Swift version migration tools from Xcode. Meanwhile, old Objective-C code still Just Works™. I continue to write ObjC today, with no regrets. Another thing I love is that you can import open source C projects with no changes whatsoever. Compiling is much faster. The debugger actually works (though Apple has been making it worse lately). There are so many practical advantages to Objective-C, even if it's not the most "beautiful" language. Objective-C has always valued pragmatism over idealism, as the marriage between high level object-oriented programming and low-level systems programming.
