Failing builds for custom dist on arm64 iOS simulator

[chabad360]

When trying to run for iOS, it fails to build with the following error:

NY792:front_end user265210$ flutter run

Upon some further testing, it seems this is only an issue if I set SERIOUS_PYTHON_IOS_DIST. If I leave it unset, the build succeeds, but I'm missing my dependencies (namely, pandas).

Additionally, it seems to have something to do with building on an Apple Silicon mac. The release dist only includes xcframeworks for ios-x86_64-simulator not ios-arm64-simulator (or rather ios-arm64-x86_64-simulator), while building with Kivy on Apple Silicon, only produces arm64 items.

After further digging, it seems pretty clear that there is hard coded support for the x86_64 simulator and that is getting in the way of the arm64 one working. I can't figure out for the life of mine what needs to be changed (I looked in a lot of places), but at this point I properly give up.
