We'll respond shortly.
We discovered when we cloned an xcode project for a client that our specs would throw EXC_BAD_ACCESS exceptions all over (seemingly because views have been allocated but not initialized).
The solution suggested was:
Don't .gitignore your Xcode schemes. Doing so will cause ENV vars that you set in your scheme not to be shared across computers.
You also have to explicitly share your scheme from within Xcode.
