Protocol where each `Output` conforms to about swift-openapi-generator HOT 3 OPEN

Hi @laurensvm,

this sounds similar to #522 - would that cover your use case as well?

Hi @czechboy0 ,

Thanks for your quick response.

Yes, this middleware should cover the logging/tracing part of the use case. However, I would also like to present the errors in a standardized way to the UI. In the example, ErrorResponse is a generic response that is consumed by the calling SwiftUI component.

I think having a generic Output such as OpenAPIResult in the example has added value in order to handle generic errors and to avoid code duplication. Right now I have to handle the possible Components.Responses.ErrorResponse's in each of the routes separately. The alternative is to ignore the error using try? await self.client?.GetComments(path: .init(id: id)).ok.body.json, but I feel like this solution disregards a lot of useful information.

Is it expected to do this for all the routes?

Thanks again for this package, I'm still very much a fan.

The challenge here is that every operation might have completely different set of responses, and those responses might have different payloads. So you as the user familiar with your OpenAPI document can write a type like OpenAPIResult, but the generator can't know - because it treats every operation separately.

So my current recommendation would be to write an extensions/macro for your own project, with the requirement that all operations have identical non-success responses, and get some value out of it that way. And if you have ideas of how the generator could help here, please do share them. But I don't see a straightforward way to provide what you're asking right now in a way that generalizes to all OpenAPI docs.
