Nice library I am working on an integration. I believe the podspec integration is basically broken. The biggest problem is you are bothing driving a dependency on ZipArchive but then also including the ZipArchive as source code. So basically you end up with duplicate defintions.
I would recommend moving to integrate pods in the project source code yourself so you can have ZipArchive integrate by a pod project, as opposed to just copying in 3rd party code. This also woudl mitigate problems with our pod projects that use the same libraries.
Thanks for the hint. Today, I submitted version 0.10.2 to the cocoa pods main repo. Someone pushed a version 0.0.1 (?) before, don't know how it got there.
The ZipArchive source files have also been removed.
