So, the new beta SDK of iOS released last night has "App Transport Security" which encourages developers to use https instead of http. In principle, this is a great idea, and I already use https in our staging/production environments. However, I don't have https set up in my local development environment, when the iOS app is connecting to a web service I'm running on my laptop.
From a bit of playing around this morning, it appears that the URL loading system will, even if you hand it an http URL, decide to use https instead. Does anyone know how to disable this behaviour -- even just for particular URLs?
