Corinne Krych we have it already here:
https://github.com/CocoaPods/Specs/blob/master/Specs/DiffMatchPatch/0.1.2/DiffMatchPatch.podspec.json#L15

However not sure the name of the lib is that good. Check this search on CocoaPods:
http://cocoapods.org/?q=DiffMatchPatch

Perhaps AeroGearDiffMatchPatch ? we still can continue giving credits to original authors, like done today
