I had the same issue with Xcode... black screen on launching apps, no debugging and clicking would lock up Xcode.

I finally found the problem... following the lead that the simulator could not connect to Xcode I took a look at my etc/hosts file and found that months ago to solve a different issue I had edited the host file to map localhost to my fixed IP instead of the default... my value:
