 The purpose of Swift OpenAPI Generator is to generate Swift code from OpenAPI documents. As part of that process, names specified in the OpenAPI document have to be converted to names in Swift code - and there are many ways to do that. We call these "naming strategies" in this proposal.
 
-When Swift OpenAPI Generator 0.1.0 went open-source in May 2023, it had a simple naming strategy that produced relatively conventional Swift identifiers from OpenAPI names, however when tested on a large test corpus of around 3000 OpenAPI documents, it produced an unacceptably high number of non-compiling packages due to naming conflicts.
