When sending the resume
method on a NSURLSessionUploadTask
using a background client, NSURLSessionConfiguration:backgroundSessionConfiguration:
, the process never begins. I can not reproduce on simulator, only on the device, and only on 8.0.
This is not an issue regarding discretionary background tasks, resume
is ran in the foreground and literally, nothing happens. No delegation callbacks, no progress, no crashes, no network activity, nothing.
