Hello,
Recently, for my study at school, I need to develop an app which could tag each data flow(TCP or UDP) with which app it comes from. In that case we can get a <data flow, app name> tuple, and this could do a lot help for our study.
I'm wondering that is there any good suggestions to make that possible? Does NetworkExtension know which app the data flow come from when it handle with the data flows? I've googled and searched for answers, but the result are not satisfying.
I've noticed that on my iPhone8 with iOS 11, the System offers us the information of how much cellular data each app has used. Will this API be opened to us or is there any alternative methods to implement that function?
Thank you if you could help me!
