Wow, this is huge. Is the goal really to have a new language better than Objective-C, and to actually use it in projects, or mainly to demonstrate what an AI can do? As far as I understand, there is a non-trivial optimiser, assumingly also generated by AI, including the associated IR and lowerings. Are there comparisons of the resulting machine code quality and performance compared to e.g. GCC? Did you design and specify the xc language, and did the AI implement the frontend based on your specification, or was it a "full package" AI approach? (sorry if some questions were already answered on the web sites and the code, but it was too much to quickly get the answers)
