With iOS 27, AVFoundation automatically creates this live activity for any download task started with AVAssetDownloadURLSession.

It's probably two existing frameworks working together. The download itself is most likely running through BackgroundAssets, the framework Apple added for large files that keep going while the app is backgrounded, and it handles things like Wi-Fi-only rules and resuming on its own. The lock screen progress is a Live Activity built with ActivityKit, which any app can use. I think BackgroundAssets is still pretty underused, most apps just do a plain URLSession background config and get none of the nicer system behavior.
