What is the future of Objective-C?
Will Apple continue to support it, or will we wake up one day to find that Swift is the only viable language?It's a serious question. Careers depend on it. I don't accept the "No comment" approach that Apple usually takes. It's cruel.I'm willing to put the time into learning Swift if I have to. I'm not going to do it if I don't. I want to know.Frank

Update or remove Ruby 2.6
macOS Tahoe ships with Ruby 2.6.10 which was End Of Life in April 2022 (https://www.ruby-lang.org/en/downloads/branches/). How can I either upgrade it to Ruby 3.4.7 or delete it, so that my mac meets minimum cybersecurity requirements? I use rbenv for more recent versions of Ruby at the moment so don't need any suggestions on how to do add them, I just need rid of the dangerously out of date system Ruby, thanks.

Python Ignoring Invalid Distributions
Hi There, I have been using my Mac Studio to complete some work in Python (which I normally do in Linux) and recently I got this error which has completely stopped all development as venvs will no longer work correctly: WARNING: Ignoring invalid distribution ... (and then whichever apps are currently installed in the venv This occurs for me on every install of any version of Python installed using any of the standard methods (installer). I've tried all the main points of advice on knowledgeable forums, but the difference between Python on Sequoia and Python on Linux is enough such that I am at an end of my debugging knowledge. I've even attempted to blast away any System Python changes with a recovery reinstall, but the problem persists. I've done almost exactly the same setup on my MacBook Air and it is fine ... but the Studio is now unavailable for Python development. I know I have probably dropped the ball somewhere but can't see the error myself so, I'm wondering if I should just blast away everything on the machine and go through the process of doing a clean install. Asking the experts in MacOS here so I can avoid the pain of doing that!

Tkinter module in Python 3 is broken on macOS 26
When I try to invoke the tkinter module in Python 3 that is bundled with Xcode Developer Tools, I get a message saying that my system version is too low: $ /usr/bin/python3 -m tkinter macOS 26 (2602) or later required, have instead 16 (1602) ! zsh: abort /usr/bin/python3 -m tkinter It seems like the system version reported is macOS 16, which I assume is the version code before the decision to rename all OS platforms to 26. This is a very low level mistake and should be fixed as soon as possible.

C function in library code gets stripped when distributed
This is a continuation of https://developer.apple.com/forums/thread/795348 I rambled too much and did not understand the underlaying problem. The problem is that I have a C function in a iOS library. I want to call this C function from a dylib that this library loads on runtime. When running directly from Xcode (either in debug or release mode) this works correctly. However, when the app is uploaded to testflight or distributed for debugging then the function is stripped and a null function pointer exception crashes the app. In the last post it was really hard to explain and I was pressed on time but I've created a minimal reproducible example: https://github.com/ospfranco/dylib_crash The instructions to run and reproduce the crash are on the README.
