We discussed this offline, this is the PR https://github.com/apple/swift-openapi-generator/pull/538 reopened again, so that we can finish it up even while the original author is busy 🙂 Thanks @arthurcro for adding you both to the commit, it's important that we give credit to @kstefanou52 for the work already done!

Sorry, I couldn’t find the time to complete this PR yet. I made some progress, but there seems to be an issue with the unit tests—possibly something with the runtime library. I’ll have some time this weekend, so if @arthurcro would like any help, please let me know.

Thanks for the update @kstefanou52! I've got some availability this weekend too and would be happy to help . If you'd prefer to complete it yourself given the progress you've made, that's completely fine - just let me know what works best for you!

Thank you so much for the understanding @arthurcro. I'm just giving it a try and I will let you know about the outcome until Sunday end of the day.
