pyobjc-framework-ApplicationServices crashes on import without pyobjc-framework-CoreText but does not include Python dependency metadata about it

[glyph]

Describe the bug

pyobjc-framework-ApplicationServices should install_requires pyobjc-framework-CoreText, since pip install-ing it by itself causes an error.

Platform information

• Python version

3.11.6

• How was python installed (python.org, anaconda, homebrew, ...)

python.org

• macOS version

  ProductName:        macOS
  ProductVersion:     14.1.1
  BuildVersion:       23B81

To Reproduce

In a new virtualenv:

Expected behavior

I would not expect to see those tracebacks.

Thanks for the report! This was the only significant missing requirement, but I found some more when scanning for the issue:

* pyobjc-framework-ApplicationServices depends on pyobjc-framework-CoreText but doesn't require it
* pyobjc-framework-CoreServices depends on pyobjc-framework-Cocoa but doesn't require it
* pyobjc-framework-ScreenCaptureKit depends on pyobjc-framework-Cocoa but doesn't require it
* pyobjc-framework-libdispatch depends on pyobjc-framework-Cocoa but doesn't require it
* pyobjc-framework-libxpc depends on pyobjc-framework-Cocoa but doesn't require it
