Trying to build from master kivy-ios on macos x 15.1.1 with cython 3.0.11

buildozer -v ios debug

eventually results in this failure.

Also tried running against the kivy-ios renovate/cython-3.x branch. same issue.

[hemna]

I have also tried installing an old version of macOS, 14.6.1 and an older version of Xcode 15.4, using the main kivy-ios branch
with cython==3.0.0.

Same exact failure. How do you make this work?

[hemna]

you can't use cython==3.0.0 even though the documentation says so.

[damies13]

This looks like the same issue I ran into, so do we

• just use cython i.e. let it take the latest one?
• don't use cython at all?

do you have a working build script I can use as a reference?

[damies13]

so simply removing the ==3.0.0 and having only cython seemed to work for me
