Simulator in use? URGENT
Ok so I am making the ribbit app and it was working just a second ago. Now it is saying simulator in use. (The Simulator can't be launched because it is already in use.) This doesn't make sense because it is not running. Does anyone know how to fix this?

I've normally solved the problem by a) restarting the simulator or b) restarting xCode.
In the case of a), a make sure that the simulator program is actually shut down, not just closed. Closing the simulator window does NOT terminate the simulator program. Just command-tab over to the Simulator icon and then use the menu to quit.
That is what has worked for me in the past. Hope this helps!
