In this talk, I answer all your questions about App Transport Security: What is it? Why does it matter? How do you make your server compatible with it, and how do you configure your app to talk to non-compliant servers? Which other apps are using ATS? How does it work alongside other security strategies, like using plain old HTTPS or certificate pinning?
