I'm stuck at the same step too...
Here's my error:

I tried reinstalling Cocoapods (removing ALL its gems, and downloading them again), downloading xcodeproj v1.5.4 and working in parallel with 1.5.7, nothing changed :/

Exactly the same problem. Please fix this guys, we cannot continue working until it is.
