cocoapods 1.0.0 beta 6 support

[Konstantin Bychkov]

Updated to cocoapods 1.0.0 beta 6 from 0.39.0.
Can't compile your lib as pod.

got this error:

error: SwiftString/SwiftString.bundle: No such file or directory

From what I see you have these lines in .podspec

s.resource_bundles = {
    'SwiftString' => ['Pod/Assets/*.png']
  }

As far as there is no image files under Pod/Assets/I assume new cocoapods doesn't build anything to bundle.
