My Swift / iOS9 framework \'viewer_protocol\' uses another and external Objective-C framework (CocoaAsyncSocket). I\'m using Carthage to build CocoaAsyncSocket. So far everythin
Just for completeness if your header is set to public in :
Build Phases > Headers
You should either
Include the import in your main header as others have mentioned
OR
Move that header to "private" if it doesn't need to be exposed
