I get the above error in Xcode when it tries to run the basic Hello World program. It builds it fine but then Xcode crashes. I have scoured the internet for a solution. The closest was making sure my Hosts file has the following: 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost I still have the problem though. Any ideas? Thanks!
