For the sake of brevity I didn't dive as deeply into the subject as I maybe should have, but the solution you get with Cocoapods to this is if you have two Pods that point at a shared dependency in another Pod you end up with just one copy. I forget how they handle version pinning as it's been a little while since I've had to actually worry about it (I do little iOS work these days) but I seem to remember that in this case the pinned version wins and if you have a version conflict it complains during the Pod installation.
