KivyMD v2 IOS runtime error ..PyInit_celeb()... (attempt 2)

[RDCB]

This is a clearer version of my previous enquiry. Maybe delete that one.

  Hello

Using KivyMD 2.0.1.dev0 on IOS (simulation or actual device) I get the run-time error:-

<module>
     from .celebi import QuantizeCelebi
   File "<string>", line 49, in load_module
   File "/Users/rdcb/venv_test2/dist/root/python3/lib/python3.11/imp.py", line 343, in load_dynamic
 ImportError: dynamic module does not define module export function (PyInit_celebi)
Application quit abnormally!

In the same simple applications KivyMD v1.2 works ok.

From this it seems that v 2.0.1.dev0 is not yet ready for full use in released applications.

The app that fails under 2.0.1.dev0 but works under 1.2 is:-

from kivymd.app import MDApp
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.textinput import TextInput

kv = """
<TextTest>:
# orientation: 'horizontal'
orientation: 'vertical'
Button:
size_hint: 1, 0.95
text: 'test button'
MyTextInput:
id: text_input
size_hint: 0.5, None
text_hint: 'input message...'
multiline: True
height: self.minimum_height
"""

Builder.load_string(kv)


class MyTextInput(TextInput):
def on_text_validate(self):
App.get_running_app().root.ids.text_input.text = ''

def insert_text(self, substring, from_undo=False):
if substring == '\n':
substring = ''
self.dispatch('on_text_validate')
return super(MyTextInput, self).insert_text(substring, from_undo)


class TextTest(BoxLayout):
pass


class TestApp(App):
def build(self):
t = TextTest()
return t


if __name__ == '__main__':
TestApp().run()

Removing the reference to MDApp (ie the first line) means the app works on both versions.

This is only a problem under IOS.

I note that it was necessary to install 'materialyoucolor' for this kivy version (otherwise it gave a run-time error saying it was missing.

Any ideas gratefully received.

This looks like a known KivyMD issue. See: https://github.com/kivymd/KivyMD/issues/1637

unable to build example kivymd for kivy-ios · Issue #1637 · kivymd/KivyMD Using the master version of kivy,kivy-ios and kivymd Unable to compile and run in xcode "/Users/**/Library/Developer/CoreSimulator/Devices/9F084B3B-7778-4433-99AB-8DF9A3E05CFA/data/Containers/Bundl... github.com

A user suggests trying the newest recipe for kivy-ios.

Thanks for finding that. It does have the fact that 'materialyoucolor' is involved in common.

The error I am getting is a run-time error from the IOS device (via XCode) rather than a build error.

My install (pipenv install kivy-ios presumably uses the kivy-ios recipe ?) was much later than the Mar 17th date mentioned.

I'd be interested to know if anyone at all has successfully run an IOS program using the KivyMD v2 at this point in time ?

"I'd be interested to know if anyone at all has successfully run an IOS program using the KivyMD v2 at this point in time ?"

I'd suggest asking at the KivyMD discord or in the ios-support section on the Kivy discord.  I do not think there are many IOS devs in this forum.
