Answer 1

step 1: Take downloadable file url and configure a it with a NSURLSession and its method dataTaskWithUrl.

step 2 : Integrate NSURLSessionDelegate, NSURLSessionDataDelegate method in your controller.

step 3: Take two CFAbsoluteTime variable which store starTime and assign CFAbsoluteTimeGetCurrent() and second one stopTime in didReceiveData: Delegate method.

step 4 : Count speed like this

  CFAbsoluteTime elapsedTime = stopTime - startTime;
  float speedOfConnection = elapsedTime != 0 ? [data length] / (stopTime - startTime) / 1024.0 / 1024.0 : -1;
