Use OpenAPI generator from the OpenAI API spec

[philippzagar]

Use Case

Up-to-date, maintainable and properly versioned OpenAI API library for Swift that is utilized by SpeziLLM

Problem

As of now, we're using the OpenAI package from MacPaw for SpeziLLM: https://github.com/MacPaw/OpenAI
This package definitely is useable, however, it doesn't include the most up-to-date functionality of the OpenAI API, the code is sadly poorly maintained with little to no documentation, and there are lots of inefficiencies throughout the codebase.

Solution

We use the official OpenAPI spec from OpenAI together with the https://github.com/apple/swift-openapi-generator to generate the Swift client-code for the OpenAI API.
One needs to build proper wrappers on top of the generated code pieces, but it is definitely a good start.

Alternatives considered

Using other OpenAI API Swift packages like: https://github.com/OpenDive/OpenAIKit or https://github.com/adamrushy/OpenAISwift or https://github.com/SwiftBeta/SwiftOpenAI
Sadly, most of the packages suffer from similar problems as the MacPaw OpenAI library, as described above.
