Orta released a clever new CocoaPods plug-in to manage keys, application secrets and the like. Pretty much everything you don't want to check into your repository.
After you install the plug-in, storing the keys in the OS X Keychain and accessing them in your code becomes dead simple:
You can save keys on a per-project basis by running the command:
After the next pod install or pod update keys will add a new Objective-C class to your Pods xcworkspace.
I think this is a great example of what can be built on top of the CocoaPods infrastructure. That being said, I assume that someone will write a similar but independent script soon.
Note that it depends on the upcoming CocoaPods 0.34.
