I'm experiencing this issue in iOS 12 Beta 11 using last version of the framewor…k (3.2.1). The complete error localised description is: ``` HTTP load failed (error code: 53 [1:53]) 2018-08-30 11:54:43.390749+0200 Background[2224:809685] Task <7CD7B0DD-2CE2-400D-AC02-D66C0F4E4847>.<7> finished with error - code: 53 2018-08-30 11:54:43.391271+0200 Background[2224:809125] Task <7CD7B0DD-2CE2-400D-AC02-D66C0F4E4847>.<7> load failed with error Error Domain=NSPOSIXErrorDomain Code=53 "Software caused connection abort" UserInfo={_NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <7CD7B0DD-2CE2-400D-AC02-D66C0F4E4847>.<7>, _kCFStreamErrorDomainKey=1, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <7CD7B0DD-2CE2-400D-AC02-D66C0F4E4847>.<7>" ), _kCFStreamErrorCodeKey=53} [53] failure The operation couldn’t be completed. Software caused connection abort ``` The bug is easy to reproduce: you have just to put the application in background, wait for few seconds and restore it to foreground state. I've reproduced it in a blank application, that I'm attaching there. Feel free to ask if you have any doubts :) Giovanni [Background.zip](https://github.com/AFNetworking/AFNetworking/files/2335831/Background.zip)

Is it possible to observe is URLSession has outstanding data tasks (I want invalidate background task as soon as it’s empty)? operationQueue.operationCount property is not reliable, as well as for delegate queue. Store all the data tasks for session and remove them seem to be a solution but I think not the perfect one.
