I published a tool that analyzes JSON data and generates Swift data model code, named json2swift. This tool helps eliminate most of the error-prone grunt work involved with consuming JSON data in a Swift app. The repository’s README has more details.
This has been an interesting project to work on, especially building a type inference engine, as described here.
