+                So, in order to make sure that the Chat SDK continues to work once ably-cocoa 1.2.37 is released, let's temporarily lock the ably-cocoa dependency to 1.2.36, and release a new version of the Chat SDK. Then, once ably-cocoa 1.2.37 is released, we can release another version of the Chat SDK that requires 1.2.37 and above.
