Unfortunately I haven't heard from the maintainer so I can't make any more progress on this

@DanielBok ? Can you have a quick look at this?

I'll take a look at it

I have done some investigation over the past few days to figure out what is causing these builds to fail. Looking at the logs I found two issues (1) swig not found and (2) numpy not found. I solved the swig issue by simply not installing it with pip and relying on the version installed by brew (maybe this is suboptimal, not sure). I solved the numpy issue after searching for a very long time and eventually found this issue numpy/numpy#2434 which recommends to add numpy to setup_requires in setup.py. That indeed fixed that issue as well and I can now say that I have successfully built nlopt wheels for py310, 311 and 312 on macos-14 (arm64).

My fork is here where I have published the aforementioned wheels as well.
