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
