Is this SDK still usable?

[andrew-shoonya]

It is not clear that this library is even usable any more. It has not been updated in four years. It is in Objective C. It is compatible back to iOS 9, which is seven full versions ago. It has itself a version number of 2.0.0; the Clever API is up to 3.0, though it is not clear that there is any relation between the SDK version and the API version.

I have the same concern - could someone @ clever address this question please? I actually do want objective-c, but the lack of any updates in so long concerns me that this library may be obsolete.
