A Swift model generator like the Objective-C JSONAccelerator. Formats and generates models for the given JSON and also breaks them into files making it easy to manage and share between several models.

  • The models that are generated depend Swift’s inbuilt Codeable feature making encoding and decoding objects a thing of the past.
  • Allows to opt for either optional or non-optional variables.
  • Allows an array of a certain object type with different properties to be merged into a single model with all properties.
  • Click Load folder with JSON files + Config to generate all possible models for given folder with JSON files, note this needs a .config.json as this uses the CLI logic internally.


  • CLI tool needs to be recreated
  • Tests needed to be added again
  • Sparkle integration to deploy newer versions
  • Deployment using homebrew
  • Add support for Codextended.
