FYI This is I think similar to the issue I have seen with core.camera where the camera provider is hidden by the kivy-ios libkivy.a name space and the dynamic loader can't find it. In that case I was able to work around by patching the dynamic loader with a static import statement. https://github.com/RobertFlatt/kivy-ios/blob/master/kivy_ios/recipes/kivy/kivy_core_camera.patch As such it looks to me like a kivy-ios design issue.

In this case it is probably the library register https://github.com/kivy/kivy/blob/master/kivy/core/image/__init__.py#L992 that fails for the same namespace reason.

I assume the potential cases are

0000000000000000 T _PyInit_kivy_core_audio_audio_sdl2
0000000000000000 T _PyInit_kivy_core_camera_camera_avfoundation
0000000000000000 T _PyInit_kivy_core_clipboard__clipboard_sdl2
0000000000000000 T _PyInit_kivy_core_image__img_sdl2
0000000000000000 T _PyInit_kivy_core_image_img_imageio
0000000000000000 T _PyInit_kivy_core_text__text_sdl2
0000000000000000 T _PyInit_kivy_core_text_text_layout

thanks, @RobertFlatt i was able to solve this issue by specifying pil and sdl at the top of my main file as KIVY_IMAGE. something like this,

import os
os.environ['KIVY_IMAGE'] = 'pil,sdl2'

and the above works fine
