Argo is a functional JSON parsing library for Swift that extracts type-safe models from JSON with explicit failure states. It was inspired by the Haskell Aeson library and uses Swift's type system to eliminate manual validation code.

Use cases

  • parse json into swift models
  • type-safe json decoding in ios app
  • avoid writing manual json validation code
  • functional json parsing library for swift
  • map api responses to model objects
  • handle missing or mistyped json fields gracefully

When to choose

  • you want concise, type-safe JSON-to-model decoding in Swift
  • you prefer a functional programming style with explicit failure states
  • you're on an older Swift codebase already using Argo or Runes

When to avoid

  • you're starting a new project - Swift's built-in Codable covers most needs
  • you need a library actively updated for the latest Swift versions
  • you want JSON decoding without functional programming dependencies like Runes or Curry
