Share extension support

### Question

I'm trying to access the generator swift package inside a Share Extension.


I get this error when building: `_OpenAPIGeneratorCore is only to be used by swift-openapi-generator itself—your target should not link this library or the command line tool directly.`

Please let me know what I'm doing wrong or how to get access to the generator. Thank you.

Start by reproducing the build in the Share Extension and inspect how the generator Swift package is linked. Use the reported error to determine the supported integration path; done means the Share Extension can access the generator without directly linking _OpenAPIGeneratorCore or the command-line tool.
