AI-generated Key Takeaways
GCKUIImageCache is a protocol in the Google Cast SDK for iOS that defines how to retrieve and cache images, primarily used for media artwork displayed in the user interface.
A default implementation of GCKUIImageCache is used internally by the framework, but applications can provide a custom implementation.
The protocol includes an asynchronous instance methodfetchImageForURL:completion:which fetches an image from a given URL and returns a scaled version via a completion block on the main thread.
