回答1:
The most common cause of these kinds of crashes is a corrupted DerivedData directory. You can delete this directory (and many of us do this regularly, just to keep things more stable).
- Open Xcode
- Preferences
- Locations
- The Derived Data option will tell you where your directory is
- Delete that directory
- Try to open your project
Personally, I select "Custom" for Derived Data, and put it in /tmp/xcode-build. This deletes the directory every time I reboot, and is easier to type than the default when I want to delete it by hand.
EDIT: One more common problem: you often need to reboot after upgrading Xcode. Since Xcode 5, that's been less of an issue, but it's still worth trying, especially if you're upgrading from Xcode 4.

Nothing work for me. I delete my .xcworkspace and regenerate .xcworkspace by pod install and work for me. but take a backup before you do so.
