## What it is
JSONKit is a very high performance Objective-C JSON parsing and serializing library for Mac OS X and iOS. It predates and outperformed NSJSONSerialization but has not been actively maintained since around 2011.

## Use cases
- parse json in objective-c on ios
- serialize nsdictionary to json fast
- high performance json parsing for ios apps
- convert json to nsarray and nsdictionary
- faster alternative to nsjsonserialization

## When to choose
- you are maintaining a legacy Objective-C codebase already using JSONKit
- you need maximum JSON parse/serialize speed on old iOS targets

## When to avoid
- starting a new project - use NSJSONSerialization instead
- you need maintained, supported code with a clear license file
- you target modern Swift-first codebases

## Facets
- artifact type: library
- maturity: abandoned
- function: serialization, parser
- domain: developer-tools, apis, mobile-development
- platform: cpp
- tags: objective-c, json, high-performance, legacy, macos, ios
