Update version with SPM support

[taimiketaiTM]

@nachoBonafonte I noticed that you have a PR open (#20) that fixes an issue for protocol inheriting with Swift. I was wondering if you could merge that PR and update the release version so that the Cocoapod version would also have that fix and be up to 0.5.2 (where your forked branch has those changes). Thanks for the fix!

Sorry, but I am not an admin on the project and have no rights for that, maybe @austinlparker or @bhs can help you with it.
