KFSwiftImageLoader

KFSwiftImageLoader is an extremely high-performance, lightweight, and energy-efficient pure Swift async web image loader with memory and disk caching for iOS and  Watch.

This is the world’s first  Watch-optimized async image loader with WKInterfaceImage extensions and intelligent automatic cache handling via WKInterfaceDevice.

Features:

• WKInterfaceImage, UIImageView, UIButton, and MKAnnotationView extensions for asynchronous web image loading.
• Memory and disk cache to prevent downloading images every time a request is made or when the app relaunches, with automatic cache management to optimize resource use.
• Energy efficiency by sending only one HTTP/HTTPS request for image downloads from multiple sources that reference the same URL string, registering them as observers for the request.
• Maximum peformance by utilizing the latest and greatest of modern technologies such as Swift 3.0, URLSession, and GCD.
