I am trying to debug some inconsistent behaviour I am seeing in an application that gets its primary data from the internet. I don\'t see the issues in the simulator, just
I would suggest you using Charles Proxy app on Mac
It allows you using Bandwidth Throttle
feature that was created just for adjusting network connection
Star/Stop Throttling ⌘ command + T
Throttle Settings... ⌘ command + T + ⇧ shift
*If you create you own Preset via Add Preset
with Bandwidth 0 and 0 for Download and upload you can simulate no Internet connection. Also it is very useful to enable it only for some specific hosts
As an alternative you can disable your connection on Mac because all traffic from Simulator go thought your computer
