Hello, I'm trying to submit an app to apple connect that is build outside of xcode but I'm getting this email saying the files have an invalid signature. I'm doing a step wrong or maybe using the wrong signature but not sure what is supposed to be the way to do it.
The app is written with python and pyside, and packaged with pyinstaller.
In the pyinstaller .spec file I set the codesign_identity and entitlements_file and also fill some things to the info_plist (CFBundleVersion, LSApplicationCategoryType, etc).
This results in a .app file, which then I run a command on it:
productbuild --component path/to/file.app /Applications path/to/file.pkg --sign <id>
And then push with:
xcrun altool --upload-app path/to/file.pkg --type macos -u <username> -p <password>
I'm able to upload but then I get the email with the signature error (ITMS-90238: Invalid Signature).
Are these steps ok, or something else is needed?
