Hello everyone, this is my little #MARCHintosh project:

Altivec Intelligence is a containerized cross-compile environment that is built for retro tech-enthusiasts that want to build software for their retro Mac and iOS device. It builds Mac apps that run on all Macs with 10.4 Tiger and up including PowerPC, Intel, and Apple Silicon Macs. The iPhone toolchain can build apps that run on iPhone 3GS with iOS 4.3 and later.
Why include AI? Building apps that target these old platforms requires using old Objective-C that does not have the syntactic sugar provided by Objective-C 2.0 or Swift. So the AI will help with that by ensuring you are only using old APIs, helping you solve warnings, and typing out the very verbose Objective-C with no Properties, Automatic Reference Counting, or Block Syntax.
In the end, I think everyone that is a fan of retro Macs has an app idea or two that would make their old Mac more useful to them. But because of lack of time or lack of desire to program old-school Objective-C, they have never gotten around to building it. I hope that Altivec Intelligence will empower this niche community to make our favorite retro-tech more useful in the modern world.

I created a demo video, but keep in mind I am not a professional YouTuber, so please forgive the bad cuts and monotone voice.
I know AI can be a controversial topic, but just know you can use this system completely without AI if you prefer.

I found the demo of it doing agent tasks with AppleScript pretty neat - Apple was ahead of its time with some deep and easy to use integrations into the OS with AppleScript - it just never caught on in a meaningful way. Did you have to train the model to know about AppleScript API's or how did that work?

I have used AI to write Applescripts (and it is much better than I am at AppleScript). But for this project, it's pure Objective-C assistant. This doesn't try to automate tasks on old Macs. It just helps you vibe-code apps that will run on old Macs.
