## What it is
Unbox is a lightweight Swift library for decoding JSON into model objects with minimal boilerplate. It is now deprecated in favor of Swift's built-in Codable API and the Codextended project.

## Use cases
- decode  into swift model objects
- parse  api responses in an ios app
- map  dictionaries to swift structs
- handle optional and required  fields when decoding
- convert  data to typed swift values

## When to choose
- maintaining a legacy Swift codebase that already uses Unbox
- working on an old project targeting Swift versions without full Codable support

## When to avoid
- starting a new Swift project - use Codable instead
- you need a maintained library with ongoing support
- you want encoding as well as decoding

## Facets
- artifact type: library
- maturity: abandoned
- function: serialization, parser
- domain: developer-tools, backend, mobile-development
- platform: -
- tags: -decoding, deprecated, swift, model-mapping, ios, macos
