At the April 2017 Melbourne CocoaHeads meetup I presented on using Swagger Codegen to automatically generate a Swift 3 API client based on a Swagger spec.
I started with an introduction to Swagger using a spec for the Melbourne CocoaHeads Events API spec and implemented a basic CocoaHeads iOS project.
At the September “Swift 4” meetup I presented a quick five minute demo generating Swift 4 code from swagger codegen. The main purpose was to show the reduction in the amount of boilerplate code generated for Swift 4.
