URLSessionProxyDelegate configuration for devices

[mmmcheese]

I have added URLSessionProxyDelegate.enableAutomaticRegistration() to my project in the AppDelegate to track all network activity. This works on the simulator, but I've noticed that it does not seem to work on device. Interestingly, the demos in the Pulse repo do log the network activity on a device. Is there something I need to do besides adding that line to my project to make this work?

Seems like public override func responds(to aSelector: Selector!) -> Bool in URLSessionProxyDelegate never gets called on a device. I've tried iPad, tvOS, iPhone. It all works on the simulator.

Actually, on further inspection the issue is that on device, swizzling is not taking place. I don't understand why.

Error logs also indicate the swizzling is incorrect on device.

I think we could do something like this to Nuke to avoid swizzling.

I spent some time trying to debug it, and it's not clear to me why it doesn't work. I've tried a fresh project and did swizzling myself in a simple app, and it worked. But this one doesn't work for some reason...I wish I knew why.

@kean I haven't happened to make any progress on this. It works great on the simulator, but not on device.
