My iOS 9.3 app uploads large (100MB) video files to a backend OS X server for processing. If I use write(2) on a socket from a background thread, it works but I get no feedback on the progress of the upload until it's completed. And if the transfer gets interrupted, it must restart from the beginning.
I've noticed that certain classes such as AVAssetExportSession provide a 'progress' property, so I'm wondering:
1) Is there a better way to accomplish large data transfers?
2) Is there a way that provides progress information?
3) Is there a way that provides checkpointing in case of interruptions?
