Spec repo not compatible with older CocoaPods versions
On Nov 11, 2016, the CocoaPods team introduced a breaking change that affects customers using 0.x versions of CocoaPods.
You can read the the details of this change on their blog here: https://blog.cocoapods.org/Sharding/
If you are using an older version of CocoaPods, you might start seeing
failures in buddybuild. You would very likely see the same errors if you
pod install locally.
There are a few options you can try:
Upgrade to CocoaPods 1.x
Podsfolder into your git repository
