## What it is
BrightFutures is a Swift library implementing futures and promises for asynchronous programming, offering a functional alternative to completion blocks with typesafe error handling. It has reached end-of-life as Swift's built-in async/await makes it obsolete.

## Use cases
- write asynchronous code in Swift with futures and promises
- replace completion blocks with composable async results
- handle errors typesafely in async Swift code
- chain asynchronous operations in iOS apps
- migrate legacy promise-based code to async/await

## When to choose
- maintaining an older Swift codebase already using BrightFutures
- working in a Swift version without async/await support
- you prefer functional futures/promises over completion handlers

## When to avoid
- starting a new Swift project - use built-in async/await instead
- you need an actively maintained dependency
- targeting modern Swift concurrency features

## Facets
- artifact type: library
- maturity: abandoned
- function: concurrency
- domain: developer-tools, mobile-development
- platform: -
- tags: futures, promises, async, swift, end-of-life, ios, macos
