Unable to subclass AsyncMessagesViewController

[swbrenneis]

After installing the pod in XCode 9, I am unable subclass or otherwise use AsyncMessagesViewController. All other dependencies (SLKTextViewController, etc.) are accessible. I have deintegrated and reinstalled my pods. All other pods work.

Sadly, the latest release was not tested carefully, my bad :(
This PR #18 fixed the issue you mentioned. So you can use the master to be able to subclass
However, you will probably get another issue described in #20
