Cocoa pods objective c files in Swift project. Bridging issue

I downloaded code from here:

https://github.com/QuickBlox/quickblox-ios-sdk

wich include sample-chat-swift example folder where seems somehow guys created a framework.

In my case if I just use cocoa pods to pull code into my project Xcode says to me that we can't find any of downloaded classes. So I am sure that is problem with bridging but my question what are the steps I need to do to create framework like guys did in theirs example.

Or do I need to bridge each files manually? If so I guess it can take so much time.
