Could not build Objective-C module 'JSQMessagesViewController'

Question

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.

I fixed the problem by going through the following steps:

• Clean the project, including the build cache (Command-Option-Shift-K)
• Removing the pod.lock file and the pods.xcodeproj files
• And then closing Xcode and running pod update again
• Then building again.
