Concorde is an Objective-C framework for downloading and progressively decoding progressive JPEG images on iOS and OS X, built on libjpeg-turbo. It provides CCBufferedImageView, a drop-in image view that displays images as they stream in.
Use cases
- show progressive JPEGs loading incrementally in an iOS app
- download and decode large JPEGs without blocking the main thread
- replace UIImageView with a progressively rendering image view
- display images faster on slow network connections
- integrate progressive image loading with the Contentful delivery API
When to choose
- your iOS or OS X app displays progressive JPEGs and you want incremental rendering
- you want a simple drop-in UIImageView replacement backed by libjpeg-turbo
- you use Contentful and want automatic progressive JPEG delivery
When to avoid
- you need modern Swift-first image loading with broad format support (consider alternatives like SDWebImage or Kingfisher)
- your project targets platforms beyond iOS/OS X
- you need actively maintained code with recent updates
