The other piece of magic you are doing is sending in the keystrokes / mouse movements. If you're running multiple iOS simulators on a Mac, how are the key presses / mouse movements not interfering with other users?
The one piece that puzzles me is how the frames are being captured from the iOS simulator. Are you launching multiples per user account, where each one is a different session at a different portion of the screen, and essentially screenshotting each? Or did you modify the simulator somehow and are hooking in to grab the screen, so that way its irrelevant of their position on screen?
Maybe, but then launching multiples and capturing the screen of them to send off through the sockets seems like there must be something in between. I wonder if its able to see where the session windows are on the screen and screenshotting them to send through, or if they somehow hooked directly in to pull the screen?
I understand those are the web technologies, but how is this being run in the back? Tons of mac servers, with multiple IOS simulators on each? One running per user on the mac? Custom software to control and pass through to the socket?
Care to shed any light as to an overview on how the backend works? I've always been curious since I first saw App.io
Thats a pretty sweet API, never seen that before, thanks! I'm going to play around with it a bit to see what it can do!
