Podspec issues!

[HamptonMakes]

Hi!

Seems like the most recent version of Cocoa Pods is incompatible with the last release.

I get this error when doing a "pod install" after adding the npm module.

[!] The `RNGameCenter` pod failed to validate due to 1 error:
    - ERROR | attributes: Missing required attribute `homepage`.
    - WARN  | source: The version should be included in the Git tag.
    - WARN  | description: The description is equal to the summary.```

Pretty sure the master branch has the correct update but the package available via npm does not.

I have the same issue :(

Still having the same issue

Solution: fill s.homepage automatically in the RNGameCenter.podspec during installation of the package
