## What it is
Bolts is a collection of low-level Objective-C libraries for mobile app development, originally created by Parse and Facebook. It provides a Tasks abstraction (similar to JavaScript Promises) for organizing complex asynchronous code, plus an implementation of the App Links deep-linking protocol.

## Use cases
- manage complex asynchronous code in iOS apps
- chain background operations without callback nesting
- handle deep links between mobile apps with App Links
- coordinate dependent async tasks dynamically
- avoid blocking the iOS UI thread during long-running work

## When to choose
- you maintain a legacy Objective-C iOS codebase already using Parse SDK conventions
- you need a promise-like task abstraction in Objective-C
- you need App Links protocol support in an older iOS app

## When to avoid
- you are starting a new Swift project - use Swift concurrency (async/await) instead
- you need actively maintained libraries with ongoing support
- you only need GCD or NSOperation, which cover most modern use cases

## Facets
- artifact type: library
- maturity: maintenance
- function: concurrency, developer-tools
- domain: mobile-development, developer-tools
- platform: cross-platform
- tags: objective-c, tasks, promises, app-links, deep-linking, parse, facebook, ios, mobile
