Argo

What is Argo?

Argo is a library that lets you extract models from JSON or similar structures in a way that’s concise, type-safe, and easy to extend. Using Argo, you won’t need to write validation code to ensure that incoming data is of the right type, or to make sure required data fields aren’t turning up empty. Argo uses Swift’s expressive type system to do that for you, and reports back explicit failure states in case it doesn’t find what you’ve told it to expect.

Argo is the Greek word for swift and the name of the ship used by Jason, son of Aeson, of the Argonauts. Aeson is the JSON parsing library in Haskell that inspired Argo, much like Aeson inspired his son Jason.
