Describe the bug

I'm trying to use pillow in my project and I get the following error: ImportError: dynamic module does not define module export function (PyInit__imaging)

(I understand that this issue has been closed, but I have new xcode)

To Reproduce

git clone https://github.com/kivy/kivy-ios.git
cd kivy-ios/
python3 -m venv venv
. venv/bin/activate
pip install -e .
python3.10 toolchain.py build kivy python3
python3.10 toolchain.py pip3 install pillow

Expected behavior

Trying to import Pillow in my project

Additional context

I noticed that I don't have libpillow.a in General -> Frameworks, Libraries and Embedded Content (not available for some reason)

Moreover, when I do an update to python3.10 toolchain.py [project_path], I get a series of errors:

I removed libpillow.xcframework from Link binary with libraries in Build Phases in Xcode, the project starts normally, but I get the expected error: ModuleNotFoundError: No module named 'PIL', I guess the problem is in libpillow

Kryptonh commented 2 weeks ago

Okay, after long researching I removed 2/5 files with error from libpillow.a and fixed error with importing Pillow framework in Xcode, but I still get the error:

Maybe Pillow 8.2.0 (standard recipe version for kivy-ios) too old for Xcode 15....?
