## What it is
BlocksKit is an Objective-C library that adds block-based APIs to common Cocoa and UIKit classes, removing limitations on coding with blocks. It ships as a framework for OS X and iOS or a static library for older iOS versions.

## Use cases
- use blocks instead of delegates in objective-c
- block-based uikit event handlers
- simplify grand central dispatch usage in objective-c
- add block callbacks to collection classes
- modernize legacy objective-c code with blocks

## When to choose
- maintaining a legacy Objective-C iOS or macOS codebase
- you want block-based alternatives to delegate patterns in UIKit
- targeting older iOS versions like iOS 6-8

## When to avoid
- starting a new Swift project
- you need actively maintained dependencies
- targeting modern iOS with Swift concurrency

## Facets
- artifact type: library
- maturity: abandoned
- function: developer-tools, concurrency
- domain: apple-ecosystem, developer-tools, mobile-development
- platform: cpp
- tags: objective-c, blocks, cocoa, uikit, cocoapods, ios, macos
