Could not build Objective-C module 'JSQMessagesViewController'
<p>I have two projects which both use JSQMessagesViewController, however in one of them I am getting the error: "Could not build Objective-C module 'JSQMessagesViewController'", whereas the other one works fine...There is virtually no difference between the two projects, how do I get JSQMessagesViewController to work because it is essential to my application. Thanks.</p>
