## What it is
Twitter Image Pipeline (TIP) is an iOS framework for fetching, decoding, and caching images with in-memory and on-disk caches. It supports progressive JPEG rendering, resumable downloads, and intelligent cache variant management.

## Use cases
- load images efficiently in an iOS app
- cache images on disk and memory on iOS
- render progressive JPEGs as they download
- resume partially downloaded images
- avoid redundant network fetches for uploaded images
- serve cached image variants at different sizes

## When to choose
- building an iOS app with heavy image feeds like timelines or galleries
- you need progressive JPEG and resumable image downloads
- you want a battle-tested image pipeline from a major app

## When to avoid
- building for Android or cross-platform targets
- you need a Swift-first modern library with active community development
- your image loading needs are simple enough for SDWebImage or Kingfisher
