Hint: about Swift 2 support

[superarts]

As others suggested the latest tag 0.8.1 doesn't work with Swift 2. If you really want to use it (in a non-safe way), use the master branch which works fine so far:

pod 'MotionKit', :git => '[email protected]:MHaroonBaig/MotionKit.git'

Hope the author is able to create a proper version for it, or at least let some contributors to do it.
