I can't get kivy running on my ios device with matplotlib. It freezes on my phone while I see the uploading screen.

        import matplotlib.pyplot as plt

        x = np.linspace(0, 10, 100)
        y = np.sin(x)

        fig, ax = plt.subplots()
        ax.plot(x, y, label='sin(x)')
        ax.set_xlabel('x')
        ax.set_ylabel('sin(x)')

        fig.savefig(self.temp_file)

        texture = Texture.create(size=(fig.get_figwidth() * 100, fig.get_figheight() * 100))
        texture.flip_vertical()
        texture.blit_buffer(fig.canvas.tostring_rgb(), colorfmt='rgb', bufferfmt='ubyte')

        with self.canvas:

        layout.add_widget(MatplotlibWidget())

@tcaduser Could you possibly share some working code you used to develop the recipe?

Matplotlib Compatibility:
Matplotlib is primarily designed for desktop environments and might not have full compatibility with iOS.
Limited Graphics Acceleration:
Kivy on iOS relies on OpenGL for rendering, but some features like Matplotlib plots might not be efficiently handled by the limited OpenGL support on iOS devices.

@causeri3 Can you try my project if it solve your issue: https://github.com/mp-007/kivy_matplotlib_widget
My project used an other approach by using Agg backend. The rendering will be much faster.

You can used this working example:

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
import os
import numpy as np
import matplotlib.pyplot as plt
from kivy_matplotlib_widget.uix.graph_widget import MatplotFigure

#or use this widget if you have multiple axis and not just lines
#from kivy_matplotlib_widget.uix.graph_subplot_widget import MatplotFigureSubplot


class MatplotlibApp(App):


    def build(self):
        print("app.directory = ", self.directory)
        print("app.user_data_dir = ", self.user_data_dir)
        layout = BoxLayout()

        x = np.linspace(0, 10, 100)
        y = np.sin(x)

        fig, ax = plt.subplots()
        ax.plot(x, y, label='sin(x)')
        ax.set_xlabel('x')
        ax.set_ylabel('sin(x)')
        
        figure_widget = MatplotFigure()
        figure_widget.figure = fig
        
        layout.add_widget(figure_widget)

        return layout


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

Can you run with the xcode debugger attached to your iphone and see if it crashes in the c code. I haven't worked with this recently, but I have had issues where I have needed to compile multiple times to get the code in a good state. I think there may be some caching issue between the IOS phone and phone simulator builds.

Tbh, I gave up on matplotlib and visualize the data simplified with kivy widgets. The old XCode debugging logs from the build on my iPhone are above. For the moment, I keep on struggeling to get the App on TestFlight.
