## What it is
DynamicCocoa is a framework by Didi's AppArch team for running Cocoa (Objective-C) code dynamically on iOS/macOS, enabling hot-patching of native apps. The project was announced but never fully released and has been inactive since 2018.

## Use cases
- hot-patch native iOS apps without App Store review
- run dynamically downloaded Objective-C code at runtime
- fix production bugs in shipped iOS apps
- dynamically load business logic in Cocoa applications

## When to choose
- you maintain a legacy Objective-C iOS app and need dynamic code execution despite the risks
- you want to study how dynamic Cocoa code execution was implemented

## When to avoid
- you need a maintained or supported solution
- your app targets the App Store, since dynamic code execution violates Apple review guidelines
- you use Swift rather than Objective-C/Cocoa

## Facets
- artifact type: framework
- maturity: abandoned
- function: interpreter, developer-tools
- domain: developer-tools, mobile-development, programming-languages
- platform: -
- tags: cocoa, objective-c, dynamic-code, hot-patch, didi, ios, macos, apple-ecosystem
