Best fix for __My Company.__ in XCode 4:
Open your Address Book card and give yourself a company name. You should do this from System Preferences to make sure you are changing the correct User.
On you Mac –> Select System Preferences –> Select Users and Groups –> Click once on Your User ID –> Click on Address Book Card ‘Open’ button. This is the contact associated with your User account. Add a company name here (just under your name). Close XCode if it’s open. Open Xcode and give it a try. Good luck.
