Add podspec File to use this Library with Cocoapods (branch: swift)

Hi,

i added a podspec File to use your Library with Cocoapods (only if you use the swift-branch of Cocoapods).
But its not workin, i can install your Library with "bundle exec pod install" if defined in my Podfile, but i cant use it because a framework class/module called "KeychainWrapper" allready exists.
