## What it is
Typhoon is a powerful dependency injection (IoC) framework for Objective-C and Swift apps on Cocoa and CocoaTouch. It uses the Objective-C runtime to assemble and inject dependencies, and its pure Swift successor is Pilgrim.

## Use cases
- inject dependencies into iOS view controllers
- set up dependency injection in an Objective-C app
- wire up services with Core Data and Reactive Cocoa
- make iOS code more testable with DI
- replace singletons with an IoC container
- use dependency injection with Swift and storyboards

## When to choose
- you maintain an Objective-C Cocoa or CocoaTouch app needing full-featured DI
- you want a mature, battle-tested IoC container for legacy iOS codebases

## When to avoid
- you are starting a new pure Swift project - use Pilgrim instead
- you need DI outside the Apple ecosystem

## Facets
- artifact type: framework
- maturity: maintenance
- function: middleware, developer-tools
- domain: mobile-development, developer-tools, apple-ecosystem
- platform: -
- tags: dependency-injection, inversion-of-control, ioc-container, objective-c, cocoa, cocoatouch, ios, macos, swift, mobile
