Why is importing AppKit not working when AppKit is installed on pip3?

Question

I have installed AppKit in pip3, but importing it from python3 doesn't seem to work. How can I import AppKit ?

This shows a ModuleNotFoundError . Is it under a different namespace?

如果你想使用 AppKit，你必须安装 PyObjC：

pip3 install -U PyObjC
