title: How to set up interoperability between internal Swift and Objective-C classes when developing a Framework
body: <p>I have a <strong>Framework</strong> with mixed Objective-C and Swift classes and i'd like to communicate between them keeping the Swift interface internal (without making Swift classes and methods public). Is there a way to achieve that?</p>
  <p>P.S. Please pay attention that since it's a Framework project, it's not an option to use the bridging header solution, because it's not supported for frameworks.</p>
