JSQMessagesViewController message view error

Question

I have an app that is error-free when I run in Debug mode, but when I run it in Release mode, I get this error when the message view tries to display messages:

2016-09-14 16:17:31.305 MyApp[70800:1072070] -[_TtCs19_NSContiguousString messageHash]: unrecognized selector sent to instance 0x7fa4eb461db0

I am not sure why this is the case only in Release mode, but does anyone have a fix?

It looks like the issue is in relation to the message hash of the message. Make sure that you have your message object set up correctly. In that it adheres to the

JSQMessageData protocol
