Hi
I submitted another PR earlier to the Launch Darkly iOS SDK, this is kinda similar to this PR, although I now save a strong reference to the
NSURLSession
object, and use the ephemeral session configuration, since I assume caching etc. is not really needed for the operations performed.I've also inserted a cleanup of the session each time
open
andclose
is executed to get rid of any leaks possible (they might be small and/or inferior, but our app still get's punished by iOS for them :-) )For reference, here's the other issue+PR: launchdarkly/ios-client-sdk#97
