xcode 5.0.1 and 5.0.2 crashing when creating new project everytime
The same happened to me, when i was set name for new xcode project "SendTweet", it crashed while creating. But when restart my guest mac on windows the project created. Then i try to create project with different name, this time no problem, it worked.

Again I used a name "Tweetbot", This time again crashed. Just try to create with different project name, it worked.
