Hi, Ben. ;-)I can confirm this. I'm going through an older app, making changes to debug on Xcode 7.1 and iOS 9, and in the process of figuring out the correct way to add an exception for ATS in development mode (where I can't easily use HTTPS), I've found that the simulator is unable to connect to the local Mac in surprising ways.I'm using the .local ATS exception described by Quinn in another thread, but a request to that .local address is unable to connect. When checking by hand through Safari in the simulator, I tried a bunch of different things that all should reach the same development server.http://localhost:3000/ - workshttp://127.0.0.1:3000/ - workshttp://steves-mac-pro.local:3000/ - failshttp://macpro:3000/ - failshttp://192.168.1.12:3000/ - failsThe middle one resolves via Bonjour, and I can telnet to it from a terminal (though it fails on two IPv6 addresses before succeeding with an IPv4 address). macpro will resolve in the default DNS domain to the last one.
