## What it is
A Swift library providing type-erased wrappers (AnyEncodable, AnyDecodable, AnyCodable) for encoding and decoding heterogeneous values with Swift's Codable system. It enables working with dynamic JSON-like structures where value types are not known at compile time.

## Use cases
- encode a dictionary with mixed value types to JSON in Swift
- decode arbitrary JSON without defining concrete Codable structs
- handle dynamic JSON payloads with unknown schema
- store heterogeneous values in a Codable container
- pass mixed-type data through Swift Codable APIs

## When to choose
- you need to encode or decode JSON with dynamic or unknown structure in Swift
- you want a small, MIT-licensed, dependency-free Codable helper
- you're building Swift server-side or iOS apps that consume loosely-typed APIs

## When to avoid
- you have well-defined schemas and can model responses with concrete Codable types
- you need advanced JSON path queries or manipulation rather than simple encode/decode
- you're not working in Swift or with the Codable ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: serialization
- domain: developer-tools, backend, apis
- platform: cross-platform
- tags: codable, type-erasure, swift-package-manager, cocoapods, carthage, swift, ios, macos
