我创建了一个在 Android 上运行良好的应用程序，但现在我想为 iPhone 制作它。
问题是我在 Xcode 模拟器中启动应用程序时出现错误。
我会给你完整的日志文件：

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.10 from
"/Users/new/Library/Developer/CoreSimulator/Devices/52F0DAA0-D1EC-43D8-8E54-C1D3E7811235/data/Containers/Bundle/Application/0845245F-9CE7-42A0-A2C3-F5A1B9508524/myapp.app/myapp"
* The NumPy version is: "1.26.3"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: cannot import name '_ArrayFunctionDispatcher' from 'numpy.core._multiarray_umath' (numpy.core._multiarray_umath)
The above exception was the direct cause of the following exception:

Python版本：3.12.1
Numpy 版本：1.26.3
操作系统：MacOS 蒙特利 12.7.2
我使用工具链来安装和构建库
我遵循了这个程序：https://kivy.org/doc/stable/guide/packaging-ios.html
Kivy 2.2.1 正式支持 Python 版本 3.7 - 3.11。上次我尝试 3.12 时，我也遇到了类似的依赖问题。
